*
* This file was created for use with the paKet (c)1989 program only.
*
* The top two lines must remain in this file as is. They are used
* by the program for the headings on the display window.
* The first describes the type of TNC this file is set up for and
* is displayed on the bottom of the TNC help window.
* The second is the headings for the TNC help window and this line
* should line up with the "header" data in this file.
*
* Each help item starts with its "header" which is identified by
* the "@" in the first column. This is then followed by a variable
* number of lines of detailed help for that item.
*
* Any line in this file beginning with an "*" is treated as a comment
* and is ignored by the paKet program.
*
*UPPERCASE CHARACTERS are minimum that will be correctly parsed by the TNC.
******************************************************************************
@8bitconv     ON|OFF    OFF     Pass or strip high bit in CONVerse mode.
Mode:   Packet

Parameters:
     ON  - High order bit is not stripped in Converse Mode.
     OFF - High order bit is stripped in Converse Mode.

This enables transmission of 8 bit data while in Converse mode.

If 8BITCONV is OFF, the high order bit (bit 7) of the characters from
paKet to the TNC, is removed before the characters are transmitted in
a packet. ASCII characters only require 7 bits (0-6) and the final
bit is sometimes used as a parity bit. Setting bit 7 in text
characters transmitted sometimes causes problems at the receiving end.

Bit 7 is always removed in COMMAND mode.

If you want to transmit 8 bit data, but don't want all the features of
transparent mode, you should set 8BITCONV ON and AWLEN 8.
******************************************************************************
@AAlt         ON|OFF    OFF     Determines if alt SELCAL used for Mode A
Mode:   AMTOR

Parameters:
     ON  - Use alternate SELCAL for Mode A ARQ
     OFF - Do not use alternate SELCAL for Mode A ARQ

Refer to ALTCALL command.
****************************************************************************
@ACkpriority  ON|OFF    OFF     Priority Acknowledgement feature
Mode:   Packet

Parameters:
      ON  - Priority Acknowledgement feature is enabled
      OFF - This feature is disabled.

This feature, first described by Eric N7CL, is intended to improve
performance on VHF simplex channels by giving priority to data ACKs while
holding data and poll bits long enough to prevent collisions with the ACK.

If ACKpriority is OFF and SLotmask is set to $00, the MFJ-1278 will
use normal AX-25 protocol.

Prioritised acknowledgements and slotted channel access can be
enabled or disabled independently of one another. So you could if you
wish run normal AX-25 with slotted channel access or the new protocol
without slotted channel access.
****************************************************************************
@ACKTime      n         0-250   Control ACK delay period
Mode:   Packet

Parameters:
     0 - 250  Specifies the delay, in 10ms intervals.

This command specifies the delay that occurs whenever packets are
received by the MFJ-1278 but not addressed to the MFJ-1278. This
represents the time required to send a response frame (with no I
field appended) at the baud rate being used.

For 1200 baud, this value should be set to 13 (130 ms).
For  300 baud, this value should be set to 52 (520 ms).
******************************************************************************
@ALockchar    nn        ^U      Character to lock CW receive speed
Mode:   CW/MCW

Parameters:
     nn - Specifies the character to be used to force the MFJ-1278 to
          lock its CW receive speed to the incoming signal.
******************************************************************************
@ALtcall      ssss      (blank) Define alternate SELCALL for Amtor Mode A
Mode:   AMTOR

Parameters:
     "ssss" - a set of four letter SELCALL for mode A.

This is the alternate SELCALL than the MFJ-1278 will respond to in
Mode A.
******************************************************************************
@ANsbstr      cccc      (blank) Define response to WRU signal
Mode:   AMTOR

Parameters:
     "cccc" - Defines up to 15 characters of text as the MFJ-1278's
              response to an Amtor WRU signal.

The resonse to the WRU in a mode A ARQ contact is the automatic
transmission of the ANSBSTR text.
******************************************************************************
@ARcvchar     nn        ^R      Character to return to Receive mode
Mode:   RTTY/CW/ASCII

Parameters:
     nn - Specifies the character to be used in RTTY/CW/ASCII modes
          to return to receive mode after transmitting.
******************************************************************************
@ARq          ssss      I-cmd   Initiate AMTOR mode A connection
Mode:   AMTOR

Parameters:
     "ssss" - This is the SELCAL of the other station you wish to
              connect with.

When the ARQ is first issued, the MFJ-1278 begins to key the
transmitter in an attempt to establish the link. BOth CON and STA
LEDs light to indicate the "phasing" condition.

IF the remote station answers, the STA LED extinguishes and the
MFJ-1278 is ready to accept text for transmission. Type K or CONV to
select text transmit mode.
******************************************************************************
@ASEndcha     nn        ^T      The transmit character
Mode:   RTTY/CW/ASCII

Parameters:
     nn - Specifies the character that initiates transmit state.
******************************************************************************
@ASPect       n         2       Sets FAX aspect ratio (Horiz : Vert)
Mode:   FAX

Parameters:
     n - Specifies the ratio of printed to non-printed rows of FAX
         graphics.

Valid values are 2 through 8.

The default of 2 means that for every one printed FAX row, two rows
are discarded. This is the optimum aspect ratio for HF FAX.

If your pictures seem to be elongated horizontally, decrease this
value; and if elongated vertically, increase the aspect value.
******************************************************************************
@AUTOBaud     ON|OFF    ON      Enables auto Baud rate detection
Mode:   All

Parameters:
     ON  - Attempt to synchronise with paKet's baud rate.
     OFF - Do not attempt to synchronise the baud rate.

In most cases the baud rate will already be correct as both
the MFJ-1278 and paKet remember their current baud rate settings.

This feature would apply mainly when you first connect the TNC to
paKet so you can easily change the MFJ-1278's baud rate to match the
setting in paKet. It could also be used if you have changed paKet's
settings without restarting the MFJ-1278.

If AUTOBAUD is ON at the time you power up the TNC, the MFJ-1278
will adjust its baud rate as you repeatedly press the Enter key.
******************************************************************************
@AUtolf       ON|OFF    ON      Send <LF> to paKet after each <CR>
Mode:   Packet

Parameters:
     ON  - A linefeed is sent to paKet after each carriage return.
     OFF - A linefeed is not sent after each carriage return.

This controls the display of carriage return characters received in
packets as well as echoing those that are typed in.

This command only affects what is displayed, not the data sent in
packets.

If needed, add <LF> characters to outgoing packets with the command LFADD.
******************************************************************************
@AUTOTrac     ON|OFF    ON      Auto lock CW speed to incoming signal
Mode:   CW/MCW

Parameters:
     ON  - Track CW speed changes of the other station.
     OFF - The MFJ-1278 does not attempt to track the CW speed.

When the last reception speed greatly differs from the speed
currently being received, the MFJ-1278 will automatically initiate a
LOCK. If CWSPEEDMATCH is also ON, your transmit speed is also
adjusted.

AUTOTRAC is useful for "listening" roaming the bands or for net
operation.
******************************************************************************
@AWlen        n         8       Data bits for TNC's serial port
Mode:   All

Parameters:
      'n' - 7 or 8 specifies the number of data bits per word.

This value defines the word length used by the serial I/O port.

AWLEN 8 and PARITY 0 is the required setting for paKet.

To send and receive, retaining all 8 data bits, you should use Transparent
mode (which uses all 8 data bits) or set AWLEN 8. This is for the
transmission of executable or special binary files.

Alternatively, you can use CONVERSE mode and set AWLEN 8 and 8BITCONV ON
and handle the CONVERSE mode special characters with the PASS prefix.

paKet provides several Binary File Transfer protocols which automatically
switche into Transparent mode for the file transfer, so if you use the
Binary Send or Receive options, you would not normally need to concern
yourself with this command.
******************************************************************************
@Ax25l2v2     ON|OFF    ON      Use AX.25 vers 1 or vers 2 protocol
Mode:   Packet

Parameters:
     ON  - Select level 2 version 2.0 of AX25 protocol.
     OFF - Select level 2 version 1.0 of AX25 protocol.

Version 1.0 was only implemented to allow correct digipeating from early
TNC1's of version 2.0 AX25 packets.

You would normally set AX25L2V2 ON, which is the default setting.
******************************************************************************
@AXDelay      n         0       Key-up delay for voice repeaters
Mode:   Packet

Parameters:
     n = 0 to 180, the voice repeater keyup delay in 100ms increments.

This value specifies the time the MFJ-1278 is to wait, in addition to
the normal TXDELAY, after keying the transmitter before data is sent.
Use of voice repeaters for Packet transmissions is neither desirable
nor necessary when suitable Digipeaters are available.

This command acts in conjunction with AXHANG.

The MFJ-1278 has this command implemented with 10ms increments.
******************************************************************************
@AXHang       n         0       Hang time for voice repeaters
Mode:   Packet

Parameters:
     n - 0 to 20 specifies the voice repeater hang time in 100ms
         increments.


This allows for more efficient channel usage if the repeater has a longer
hang or tail than 100ms.

If the packet controller has heard a packet sent within the hang period,
it will not add the extra delay of AXDELAY to the keyup time.

Use of voice repeaters for Packet transmissions is neither desirable
nor necessary when suitable Digipeaters are available.
******************************************************************************
@BBSmsgs      ON|OFF    OFF     Sets message format
Mode:   Packet

Parameters:
    ON  - Omits "Connect Request: xxxx" and puts other messages on new line.
    OFF - Normal operation.

Primarily useful for host mode operation of W0RLI type BBS's that
require link status messages to begin in the first output column.

The omission of the connect request message is to prevent corruption of
messages when BBS is forwarding.
******************************************************************************
@BEAcon       n         0       Set timing for automatic BEACON message
Mode:   Packet

Parameters:
    EVERY n - Sends beacon text every "n*10" seconds.
    AFTER n - Sends beacon text once after "n*10" seconds after last packet.

         'n'- 0 to 250.
              If n=0, Beacons are disabled.

BTEXT beacons are sent addressed to "BEACON" via the addresses and path
specified in "UNPROTO" command. If BTEXT is blank no beacons are sent.

The AFTER command can be used to send messages or announcements only when
packet stations are on the air and active.
******************************************************************************
@BKondel      ON|OFF    ON      Determine handling of <BACKSPACE>
Mode:   Packet

Parameters:
      ON  - <BACKSPACE><SPACE><BACKSPACE> is echoed when a character
            is deleted.
      OFF - <BACKSLASH>("\") is echoed when a character is deleted.

This command would usually be set ON when running paKet.

If you use the MFJ-1278 with a paper output display, or with a terminal
that does not respond to the <BACKSPACE> character (<Ctrl-H>), you
should set BKONDEL OFF. It works in both command and converse modes.
******************************************************************************
@BText        text      blank   BEACON message
Mode:   Packet

Parameters:
     text - Any normal text message of up to 120 characters and spaces.

BTEXT defines the text sent by the BEACON and is addressed to UNPROTO.

Multiple line messages can be sent by including the <PASS> character and
<CR> character in the text at the end of each line. More than 120
characters causes an error message and the command will be ignored.

You can clear BTEXT with a % or a & as the first character in the
text.

See also the BEACON command.
******************************************************************************
@BUdlist      ON|OFF    OFF     Select stations to be monitored
Mode:   Packet

Parameters:
     ON  - Ignore frames from stations not in the LCALLS list.
     OFF - Ignore frames from stations in the LCALLS list.

BUDLIST works in conjuction with the command LCALLS, which sets up a
call list. BUDLIST specifies whether the calls in the list are the
only ones you want to monitor or the ones you want to avoid.

You must set MONITOR ON also. To have MON ON without this being affected
LCALLS must be set to "BLANK".
******************************************************************************
@BUF          n         0-9     Address user programmable memories
Mode:   RTTY/CW/ASCII

Parameters:
     n - 0 to 9, specifies the memory buffer number.

You may load up to 10 buffers for use in RTTY/CW/ASCII modes Maximum
buffer text for each buffer is 120 characters.

A buffer is sent by pressing the ASENDCHAR character, This causes the
MFJ-1278 to enter transmit mode. Another ASENDCHAR causes the
MFJ-1278 to wait for the desired buffer number, then that buffer text
will be sent. (Refer also the the BUFKEY command)

If there is a "#" character in the text, the MFJ-1278 will replace
that character with the current value of SERIALNO, then will
increment that counter. Ideally used for contests where an
invrementing number is to be sent.
******************************************************************************
@BUFKey       nnn       <TAB>   Transmit buffer without using ^T
Mode:   RTTY/CW/ASCII

Parameters:
     nnn - Specifies the ASCII value of a key to be used to transmit
           memory buffers.
           Default value is 9 which is the ASCII value for <TAB>.

To send the contents of a memory buffer, you may enter the ASENDCHAR
(refer description in the help for BUF command). However, an easier
way is to use the BUFKEY character.

If you use the default BUFKEY value, press the <TAB> key followed by
a buffer number (0-9). The MFJ-1278 will transmit the contents of
that memory buffer, then revert to receive at the end of that
transmission.
******************************************************************************
@BUFTime      n         0       Transmit CW beacon
Mode:   CW

Parameters:
     n - 0 to 65535 specifies the time (in seconds) between automatic
         CW beacon transmissions.

         0 disables the CW Beacon.

If in CW mode, the MFJ-1278 will transmit the contents of memory
buffer 0 at time intervals specified by this BUFTIME command.

This provides a similar facility to the BEACON facility in Packet Mode.
******************************************************************************
@BWnl         ON|OFF    OFF     Cause AMTOR transmit on receipt of <CR>
Mode:   AMTOR

Parameters:
     ON  - The MFJ-1278 waits for a <CR> before sending a line of data.
     OFF - The MFJ-1278 sends each character as soon as possible.

This applies to AMTOR Mode B FEC only.

Setting BWNL ON allows you to correct any typing mistakes before
transmitting the data.
******************************************************************************
@CALIbra      -         I-cmd   Modem calibration
Mode:   All

Parameters:
      No parameters used on the command line, however when in
      Calibrate mode the following commands are available:
        <SPACE> Switch transmit audio to the other tone.
           K    Toggle PTT line on/off.
           D    Alternately pulse both tones.
           Q    Quit calibration mode.

This command can be activated at any time without altering the current
link state, although during Calibration, the TNC will not communicate with
the "outside world".
******************************************************************************
@CALSet       n         0       Count setting for modem calibration
Mode:   All

Parameters:
     n - 0 to 65535 specifies the count setting for use by the calibration
         routine.

The value of 'n' is detrmined by the frequency as follows:
   Modulator tones:
      n = (525,000 / freq) + 1

   Demodulator tones:
      n = (262,500 / freq) + 1
******************************************************************************
@CANline      n         ^X      Character to cancel a line
Mode:   Packet

Parameters:
      n - 0 to 127 specifies the ASCII character used to cancel an input
          line.

It can be entered in Hex or Decimal values such as CANLINE $18 or CANLINE
24 and is the code for the key you want to press to cancel a current
line while in edit mode.

You can only cancel the line you are currently typing as once the line is
completed with the <SENDPAC> character, it can no longer be cancelled!
To cancel more than a line use CANPAC. This and other editing features are
disabled in Transparent mode.

Note however, that if you are using paKet's Type Ahead window, this
CANLINE character would not be required because you can simply backspace
over any data in the buffer. At that stage it has not even been sent to
the TNC.
******************************************************************************
@CANPac       n         ^Y      Character to cancel a packet
Mode:   Packet

Parameters:
      n - 0 to 127 specifies the ASCII character used to cancel a packet.

This is the ASCII character code of the key you want to press to cancel a
packet while typing it in edit mode. It cannot be canceled after the <CR>
has been sent or after PACTIME has elapsed if this is enabled.

If used in the Command mode it stops all response from the MFJ-1278. Typed
again restores responses from the MFJ-1278. So if you type some command
that couses a lengthy display that you do not want, type this CANPAC
character and the data will no longer be sent to paKet. Entering the
CANPAC character again will resume normal data display.

If you are in Converse or Transparent mode, you must exit to Command mode,
then type the CANPAC character.
******************************************************************************
@CBell        ON|OFF    OFF     Send <BELL> to paKet on Connection
Mode:   Packet

Parameters:
     ON  - A bell character will be sent to paKet with a connect message.
     OFF - No bell character is included with connect message.

This is mainly used to attract attention to a connect from another
station if you are not in the immediate vicinity. A bell character will
still be issued even if MFILTER is set to filter out bell characters.

In paKet however, a bell alert will be sent on connection if you have
configured BELLS on. Refer to the Configuration-Communications Window
where you can specify the desired Bells sound. This is a function of the
paKet program and is not related to the TNC's CBELL function.
******************************************************************************
@CCitt        ON|OFF    ON      US or International standard RTTY
Mode:   RTTY

Parameters:
     ON  - Transmitted characters are translated into the CCITT
           International Telegraph Alphabet #2 before being sent.
     OFF - Transmitted characters remain in American standard
           Baudot format.

This parameter is only significant when in RTTY mode.
******************************************************************************
@CHange       -         I-cmd   Switch to Transmit - AMTOR Mode A "ARQ"
Mode:   AMTOR

Parameters:
     none - this is an Immediate Command.

The CHANGE command causes the MFJ-1278 to switch from being the Mode
A ARQ receiver to being the transmitter.

CHANGE forces the direction of the link to switch without using the
"+?" over signal.

It is valid only during a Mode A connection when you are the
receiver.
******************************************************************************
@CHeck        n         30      Connection timeout
Mode:   Packet

Parameters:
     n - 0 to 250 specifies the check time in 10 second intervals.
         0 disables this feature.

After the elapsed time with no packets your TNC will take action to
avoid remaining in the "connected" state indefinitely.

If AX25L2V2 is ON, it will initiate a check to see if the link is
still good. If no acknowledgment is received after all retries a
disconnect sequence will be initiated.

If AX25L2V2 is OFF a disconnect sequence will be initiated without
checking for link still good.
******************************************************************************
@CLKADJ       n         0       Correction factor for real-time clock
Mode:   Packet

Parameters:
      'n' - 0 to 65535 specifies the correction factor.

The correction factor is calculated as:
   relative clock speed in % = 100 - (9.16667 * 1/n)

This effectively slows the clock by adding timing loops.

If the clock is already running slow, there is no way of speeding it up.

A value of 0 means no correction.
******************************************************************************
@CMdtime      n         1       Transparent mode timeout value
Mode:   Packet

Parameters:
      'n' - 0 to 250 specifies the timeout value in 1 second intervals
            while in Transparent mode.

To exit Transparent mode, wait for 'n' seconds, then enter three COMMAND
characters (default <Ctrl-C>) less than 'n' seconds apart.

So, for the default of CMDTIME 1, wait for one second then type three
<Ctrl-C>s within one second to exit Transparent Mode.

While running paKet, please leave CMDTIME at its default setting.
******************************************************************************
@CMSg         ON|OFF    OFF     Send CTEXT on Connection
Mode:   Packet

Parameters:
     ON  - A text message is sent as first packet after connect is made.
     OFF - The text message is not sent.

The text of the message is contained in CTEXT and is sent after a
connection is made to you by another station.

This function might be useful if you leave your system running but are
unavailable to answer the connect request manually.

It is recommended you leave CMSG ON and change the contents of CTEXT
to reflect the state of your system. This is easily accomplished by
specifying an appropriate CTEXT message in both the Begin and End
Auto commands. (via the Configuration Window options).
******************************************************************************
@CMSGdisc     ON|OFF    OFF     Initiate a DISCONNECT after Connection
Mode:   Packet

Parameters:
     ON  - TNC will disconnect after ACK received of CTEXT from CMSG
           function.
     OFF - TNC will not disconnect automatically.

Use with care. This should only be used for unattended TNC's where no
PMS is desired. If set ON the PMS function cannot work as the other
station will be forced into a disconnect sequence immediately after the
CMSG is sent.
******************************************************************************
@COMmand      n         ^C      Character to enter COMMAND Mode
Mode:   All

Parameters:
      'n' - 0 to 127 specifies the ASCII character used to enter Command
            mode.

The COMMAND mode entry character is the character you type to enter
Command mode from Converse mode.

The character can be entered in either Hexadecimal or Decimal form.
Eg: $7F or 127.

For paKet please leave this set to the default of 3, which is equivalent
to <Ctrl-C>. When using Binary File Transfers, paKet needs to enter
Transparent mode and it may send <Ctrl-C>s to return to Command mode on
completion of the file transfer.
******************************************************************************
@CONMode      C|T       C       Enter CONV or TRANS Mode on Connection
Mode:   Packet

Parameters:
      CONVERS - The MFJ-1278 automatically enters Converse mode on
                connect.
      TRANS   - The MFJ-1278 automatically enters Transparent mode on
                connect.

The connection may be the result of a radio connection request from
another station or your own "Connect" command.

If the MFJ-1278 is already in Converse or Transparent mode when the
connection is made it will not change.

The NEWMODE command specifies the mode selected by the MFJ-1278 on
disconnect.
******************************************************************************
@Connect      call      none    Connect to another Packet station
Mode:   Packet

Parameters:
      'call' - may be a single call sign or multiple call signs via
               digipeaters.

Example:
      C VK7ABC               Attempt a direct connection to VK7ABC
      C VK7ABC VIA VK7RPT    Attempt a connection to VK7ABC via a
                             digipeater (VK7RPT).
      C VK7ABC V VK7RPT,VK3XX-1,VK3ZZZ
                             Attempt a connection to VK7ABC via 3
                             digipeaters.

Type the digipeaters in the sequence you wish to use to route your packets.
An error message is returned and the command is aborted if:
   - no response after RETRY attempts, or
   - the other TNC is already connected, or
   - the other TNC is attempting a connect, or a disconnect.
******************************************************************************
@CONOK        ON|OFF    ON      Allow other stations to connect
Mode:   Packet

Parameters:
     ON  - Connect requests from other stations will be accepted.
     OFF - Connect request from other station will be rejected.

The rejected connect request will result in the other station having
"*** <yourcall> station busy" message displayed on his screen. This is
extensively used by BBS's to control automated access and forwarding of
mail.
******************************************************************************
@CONPerm      ON|OFF    OFF     Make connection permanent
Mode:   Packet

Parameters:
     ON  - The current connect on the current stream will not disconnect.
     OFF - Normal operation of connects and disconnects.

This command only takes effect after connect is established. It functions
on a stream by stream basis when multiple connections are allowed.

The connection will be reestablished if RETRY is exceeded.

It is particularly useful when paKet is used as a local area network
server in 'contest' mode.
******************************************************************************
@CONStamp     ON|OFF    OFF     Time stamp Connect and Disconnect message
Mode:   Packet

Parameters:
      ON  - Connect status messages are time stamped.
      OFF - Connect status messages are not time stamped.

The DAYTIME command is used to set the date and time. (paKet will
automatically set this parameter in the MFJ-1278 when the program is
started, using the computer's date and time).

Example:
      If CONSTAMP is ON the connect message might appear as follows:
           cmd:C VK2DHU
           cmd:20:29:31 *** CONNECTED to VK2DHU
******************************************************************************
@CONVers      -         I-cmd   Force MFJ-1278 into Converse Mode
Mode:   All

Parameters:
      None

This is an immediate command to enter the converse mode from command mode.

Link connections in Packet or AMTOR are not affected and a return to the
command mode can be made by typing in the Command Mode Entry character.

Once the MFJ-1278 is in Converse mode, all characters sent to the
MFJ-1278 by paKet are transmitted by the radio.
******************************************************************************
@COnverse     -         I-cmd   Force MFJ-1278 into AMTOR xmit mode
Mode:   AMTOR

Parameters:
     none

Switches from AMTOR command mode ("a_cmd:" prompt) to the text
transmission mode.

Use CONVERSE after a connection or FEC/SELCALL broadcast is begum to
start exchanging data.
******************************************************************************
@CPactime     ON|OFF    OFF     Timed intervals for CONVERSE Mode packets
Mode:   Packet

Parameters:
     ON  - Packet timeout is used in Converse mode.
     OFF - Packet timeout is not used. In this case the <SENDPAC>
           character (usually a <CR> sends the packet.

If CPACTIME is ON, any characters which have been input will be packetised
and sent after PACTIME has elapsed since the last frame was transmitted.

This allows automatic periodic sending of packets in converse mode,
similar to full break-in CW. This allows continuous typing by both
stations.

It is recommended, however, that paKet's Type Ahead window be used
instead of CPACTIME to allow communication without the delays while
long packets are being typed.
******************************************************************************
@CR           ON|OFF    ON      Append <CR> to each packet sent
Mode:   Packet

Parameters:
    ON  - The CR character is appended to all packets sent in converse mode.
    OFF - This send packet character is stripped from all conv packets sent.

Various formatting modes can be achieved with this, SENDPAC $0D, LFADD
and AUTOLF commands if the other station reports overprinting of lines.

paKet has an automatic word wrap option at the end of lines in the
Type Ahead window.
******************************************************************************
@CStatus      -         I-cmd   Display status of all streams
Mode:   Packet

Parameters:
An immediate command to show the link status of all ten streams and
whether or not CONPERM is active on any stream.

It will also show which stream is the current one in use.
******************************************************************************
@CText        text      blank   Message sent on Connection
Mode:   Packet

Parameters:
      text - Any combination of characters and spaces (up to a
             maximum of 120 characters).

If CMSG is ON, the CTEXT message is sent as soon as another station
connects to your station.

Multiple line messages may be sent if the <PASS> (Ctrl/V) and <CR> is
used at end of line.

To clear the CTEXT buffer without issuing a RESET command, use '%' or '&'
as the first character.
******************************************************************************
@CWcall       ssss      blank   Characters sent (in CW) as AMTOR ID
Mode:   AMTOR

Parameters:
     ssss - up to 15 characters sent when you issue the ID character.


The "ssss" text is sent following the QRA ("The name of my station is
-----") signal.
******************************************************************************
@CWSEndch     nnn       000     Controls pending text in CW xmit buffer
Mode:   CW

Parameters:
     nnn - specifies the character to use to transmit data typed into
           the CW send buffer.

If this value is:
   000 - (the default) all characters are left buffered until a
         <SPACE>, a <CR> or other control character is sent.

   255 - send every character immediately without any delays.

Any other value defines the character which will cause the data to be
transmitted.

For example:
   If CWSENDCH is set to 2, a <CTRL-B> will cause the data to be
   transmitted.

<CTRL-R> will always transmit the buffer, regardless of this setting.
******************************************************************************
@CWspeedm     ON|OFF    OFF     Set CW xmit speed same as incoming speed
Mode:   CW

Parameters:
     ON  - Use the CW speed last set with the LOCK command.
     OFF - Use the CW speed set with the MSPEED command.
******************************************************************************
@DAytime      date/time none    Sets Date and Time in MFJ-1278
Mode:   Packet

Parameters:
      'date/time' - This should be the current date and time in the
                    format: "YYMMDDHHMM".

All two digit number groups must have leading zero if from 00 - 09. The
hours digits must be in the 24hr format and the year is the last two
digits.

paKet will generate this command for you automatically when the program
starts.

When the date and time are entered correctly, the TNC will echo the new
setting and if no 'date/time' is entered, the current setting is displayed.

The date & time parameter is used in CONSTAMP, MSTAMP and MHEARD if set.
******************************************************************************
@DAYUsa       ON|OFF    ON      Date/Time display format
Mode:   Packet

Parameters:
     ON  - Date is displayed in the format mm/dd/yy.
     OFF - Date is displayed in the format dd-mm-yy.

The format for entering date and time is not affected and must be as
specified in DAYTIME.
******************************************************************************
@DEAdtime     nnn       3       Basic time interval for slotting
Mode:   Packet

Parameters:
     nnn - 0 to 250 specifies the 10ms time interval used by the
           slotting procedures in calculating a random delay.

DEADTIME must be set to a value that accounts for the slowest
acceptable station on the channel. Ideally all stations on the
frequency will use the same value.

The current default is 3 (30ms) but a more reasonable value for VHF
is 30 (300ms) and for HF a setting of 12 (120ms) is recommended.
******************************************************************************
@DElay        nn        20      Delay before transmitting AMTOR
Mode:   AMTOR

Parameters:
     nn - specifies the delay (default 20ms) between keying the
          transmitter and transmitting AMTOR.

AMTOR Mode A ARQ demands a transceiver  switches quickly between
transmit and receive. Some radios are faster than others in this
regard and the delay is used to ensure all radios can be used for
AMTOR communications.

Try various delay times, and work towards reducing the value to a
minimum delay consistent with reliable operation. If you can work
Modes B and S, but not Mode A, try increasing the DELAY.
******************************************************************************
@DELchr       n         ^X      Delete buffer during transmission
Mode:   RTTY/CW/ASCII

Parameters:
     n - specifies the character to be used to erase the contents of
         the RTTY/CW/ASCII buffer during transmission.
******************************************************************************
@DELete       ON|OFF    OFF     Use <DEL> or <BACKSPACE> for editing
Mode:   Packet

Parameters:
      ON  - The delete character for editing input is <DEL> ($7F).
      OFF - The delete character is <BACKSPACE> ($08).

paKet works better with DELETE OFF.

You cannot delete past the beginning of a line.

How the TNC indicates deletion is controlled by BKONDEL.

To see a corrected display of a line after you have deleted characters,
type the REDISPLA character (default Ctrl-R).
******************************************************************************
@DIDdle       ON|OFF    ON      Synchronising for RTTY/ASCII
Mode:   RTTY/ASCII

Parameters:
      ON  - In RTTY, the MFJ-1278 will send <LTRS> when idling.
            In ASCII, the MFJ-1278 will send <NUL> when idling.
      OFF - No characters are sent while idling.

It may be desirable to continue sending some sort of data while paused at
the keyboard. It makes it much easier for persons receiving to tune
and remain tuned to your transmitted signal.
******************************************************************************
@DIGipeat     ON|OFF    ON      Allow digipeating
Mode:   Packet

Parameters:
     ON  - The MFJ-1278 will allow digipeating through your station.
     OFF - The MFJ-1278 will not allow digipeating.

Digipeating takes place concurrently with other TNC operations and
doesn't interfere with normal connections you may be having with other
stations.

HID enables automatic identification of your station if acting as a
digipeater.
******************************************************************************
@Disconne     -         I-cmd   Disconnect a packet station
Mode:   Packet

Parameters:
      None

This is an immediate command to initiate a disconnect command to the other
station with the resultant display of :-
    *** DISCONNECTED
when successful.

If a disconnect is issued while a connect is being attempted and before
the retries have been completed then the message :-
    *** retry count exceeded
    *** DISCONNECTED
will appear after the TNC ceases to attempt the connect.

Disconnect messages do not appear if in transparent mode.

A new connect from another station is not allowed until the disconnect
process is completed.
******************************************************************************
@DISplay      class     -       Display all MFJ-1278 packet commands
Mode:   Packet

Parameters:
     class - an optional paramter which may be:
             Async    - display asynchronous port parameters
             Characte - display special characters
             Id       - display ID parameters
             Link     - display link parameters
             Monitor  - display monitor parameters
             Timing   - display timing parameters

                        buffer contents, CW parameters and graphics
                        parameters.
             Health   - display thge 25 MFJ-1278 health counters.

If "class" is not specified, the MFJ-1278 will display all control
parameters and their current values.
******************************************************************************
@DIsplay      -         I-cmd   Display all AMTOR commands
Mode:   AMTOR

Parameters:
     none

This command will display all current AMTOR parameters if typed at
the "a_cmd:" prompt.
******************************************************************************
@DWait        n         16      Delay to avoid digipeat collisions
Mode:   Packet

Parameters:
     n = 0 - 250 specifying default wait time in 10 ms intervals.

The MFJ-1278 will wait the default time after last hearing a data
packet on the frequency before beginning the keyup sequence. This is
used to avoid collisions with digipeated packets because these aren't
retried by the digipeating station, but must be reinserted in the
system by the originating station.

Recommended settings for different types of operation:-
            Digipeaters          0   (  0 ms)
            Local keyboards     16   (160 ms) - the default
            BBS, Hosts, etc     32   (320 ms)
            File Transfers      48   (480 ms)

There are two parameters in the PAKET.CFG file specifying the DWAIT
settings you want to use for binary File Transfers (48 recommended) and
for normal operation when the File Transfer is completed (16 recommended).
******************************************************************************
@EASin        ON|OFF    OFF     Echo AMTOR text as it is transmitted
Mode:   AMTOR

Parameters:
     ON  - The MFJ-1278 echos typed characters as they are sent
     OFF - The MFJ-1278 echos typed characters as they are typed.

With EASIN ON, you can check channel quality. If your characters are
echoed quickly, it usually means the link is quite good.
******************************************************************************
@ECho         ON|OFF    ON      Echo all AMTOR text as you type
Mode:   AMTOR

Parameters:
      ON  - Characters received from paKet are echoed by the MFJ-1278.
      OFF - Characters are not echoed.

When using paKet you should set ECHO OFF.

paKet will display the characters you type in a different colour or
intensity to help you distinguish your transmissions from the data
received.

If you see two copies of everything you type, you should set ECHO OFF.

This command is operative only in the AMTOR command mode and works
independently of EASIN. There is a similar ECHO command for other
modes.
******************************************************************************
@Echo         ON|OFF    ON      Echo all text (all modes) as you type
Mode:   All

Parameters:
      ON  - Characters received from paKet are echoed by the MFJ-1278.
      OFF - Characters are not echoed.

When using paKet you should set ECHO OFF.

paKet will display the characters you type in a different colour or
intensity to help you distinguish your transmissions from the data
received.

If you see two copies of everything you type, you should set ECHO OFF.

Local echoing is disabled in transparent mode.
******************************************************************************
@EPson        ON|OFF    ON      Specify Epson/IBM or C. ITOH printer
Mode:   All

Parameters:
     ON  - The printer connected to the MFJ-1278 is an Epson or
           C.Itoh 8510-P (or compatible).
     OFF - The printer is NOT compatible with the Epson or C.Itoh.

******************************************************************************
@ERus         ON|OFF    ON      Insert "_" for AMTOR receive errors
Mode:   AMTOR

Parameters:
     ON  - Display a "_" character if errors are detected when
           monitoring.
     OFF - The "_" is not displayed when errors are detected.

Although Mode A is more protected from receive errors, they are
more likely in Mode L, which is the Mode A monitoring mode if you
can't hear boxth sides of the contact.
******************************************************************************
@EScape       ON|OFF    OFF     <ESC> may be sent as "$" or as <ESC>
Mode:   Packet

Parameters:
      ON  - The ESC ($1B) character is output as "$" ($24).
      OFF - The ESC character is output as unchanged.

The translation is disabled in transparent mode.

See also MFILTER for general character stripping rather than translation.
******************************************************************************
@FARnswor     ON|OFF    ON      Transmit CW in Farnswor method
Mode:   CW

Parameters:
     ON  - The MFJ-1278 transmits CW using the Farnsworth method.
     OFF - CW is sent at normal timing.

The Farnsworth method is sometimes considered useful because the
characters are sent at the equivalent of 15 WPM (with spacing between
characters to reduce the overall rate to the nominated speed). This
can help new operators reach higher speeds because it teaches letter
recognition at 15 WPM.
******************************************************************************
@FAXEop       ON|OFF    ON      User terminates end of FAX picture
Mode:   FAX

Parameters:
     ON  - The MFJ-1278 detects FAX end-of-picture.
     OFF - Disable end-of-picture detection.

End-of-picture is detected by looking for a long period of idle tone.

If OFF, the operator must manually terminate reception by returning
to command mode.
******************************************************************************
@FAXmode      n         3       Sets FAX format
Mode:   FAX

Parameters:
     n - 1 to 7 specifies the FAX format in terms of speed.

FAXMODE                     SPEED                       HORIZONTAL
                                                        DENSITY (dots)

   4               240      "         4     "              480
   5               360      "         6     "              720
   6               480      "         8     "              480
   7               180      "         3     "              400

This command is effective only when MULTIFAX is OFF.
******************************************************************************
@FAXNeg       ON|OFF    OFF     Print white as black and black as white
Mode:   FAX

Parameters:
     ON  - The MFJ-1278 prints the white areas of FAX pictures as black
           and vice versa.
     OFF - FAX pictures are printed as received.
******************************************************************************
@FAXRev       ON|OFF    OFF     Inverts all received FAX data
Mode:   FAX

Parameters:
     ON  - The MFJ-1278 will invert all received FAX data including
           synchronisation bars.
     OFF - FAX data remains unchanged.

This command is analogous to RXINVERT as used by RTTY/ASCII modes.
******************************************************************************
@FEc          -         I-cmd   Initiate AMTOR Mode B
Mode:   AMTOR

Parameters:
      None


The MFJ-1278 starts broadcasting with the AMTOR Mode B FEC protocol.

Use FEC:
      - for CQ calls because other stations cannot identify you in an
        ARQ CQ call!
      - if the desired range is longer than 22,000 miles (35000 Km).
      - for all round table contacts.
******************************************************************************
@Flow         ON|OFF    ON      Sets type in flow control
Mode:   Packet

Parameters:
      ON  - Type-in flow control is active.
      OFF - Type-in flow control is disabled.

With FLOW ON the MFJ-1278 will hold any received data, if you have started
sending, until you have completed the line you are sending.

Type-in flow control is designed to avoid confusing displays where the
MFJ-1278 can send any received data to the display while you are typing
something.

This is not a problem if you are using paKet's Type Ahead facility as your
typed data appears in a separate window until it is sent to the TNC.

paKet manages its own flow control so it is recommended you set FLOW OFF.
******************************************************************************
@FRack        n         3       Sets time interval between retries
Mode:   Packet

Parameters:
      n = 1 to 15 specifying the time (in seconds) the MFJ-1278 will wait
          for an ACK before retrying that frame.

If the path includes digipeaters the time is adjusted to allow for the
extra delays. An extra random time is added to avoid collisions.
******************************************************************************
@FUlldup      ON|OFF    OFF     Allows full duplex packet communication
Mode:   Packet

Parameters:
      ON  - Full Duplex mode is enabled
      OFF - Full Duplex mode is disabled

When FULLDUP is OFF the MFJ-1278 uses the DCD signal from the modem to
avoid collisions and acknowledges multiple packets with a single
transmission.

When ON the MFJ-1278 acknowledges each packet individually.

It should not be used unless a full duplex (split frequency or crossband)
link is implemented.
******************************************************************************
@GRAPHLf      ON|OFF    OFF     Adds extra <LF> to printer for graphics
Mode:   FAX/SSTV

Parameters:
     ON  - The MFJ-1278 issues a <LF> before the <CR> on every line of
           graphics.
     OFF - No additional <LF> is sent.

For most printers, GRAPHLF should be set ON. If you notice spaces in the
pictures, set it OFF.
******************************************************************************
@HEaderln     ON|OFF    OFF     Format for monitored packet headers
Mode:   Packet

Parameters:
      ON  - The header is displayed on a separate line.
      OFF - The header and text appear on the same line.

This is for monitored packets.

When HEADERLN is ON all monitored packets have the callsigns etc. on one
line and the text is printed on the next line.

paKet does not care which way this is set but if you prefer to have MSTAMP
and/or MRPT on, the header part of the monitored text can be quite long.
In this case it is suggested you set HEADERLN ON to make the data easier
to read.
******************************************************************************
@HEALled      ON|OFF    OFF     Redefine STA and CON LEDs
Mode:   Packet

Parameters:
When HEALLED is ON the TNC will flash the CON and STA LEDs alternately.
(This might be used to impress visitors to your shack).

Test for whether the TNC is responding to you, even if no response on
terminal.

When OFF the leds will indicate normal Connect and Status conditions.
******************************************************************************
@HId          ON|OFF    OFF     Send ID packets
Mode:   Packet

Parameters:
     ON  - Enables HDLC identification by a digipeating TNC.
     OFF - Disables identification.

The ident is yourcall with "/R" added and is output every 9.5 min. and
addressed to the UNPROTO address, if the station is digipeating packets.

The 9.5 minute timing cannot be changed.
******************************************************************************
@ID           -         I-cmd   Sends CW ID while in AMTOR Mode
Mode:   AMTOR

Parameters:
      None

When issued under the AMTOR command "a_cmd:", this causes a keyed
modulated CW identification of your station to be sent immediately.

The identification consists of the letters QRA followed by the callsign
entered in CWCALL.
******************************************************************************
@Id           -         I-cmd   Sends ID packet while in Packet Mode
Mode:   Packet

Parameters:
      None

An identification packet is sent only if the MFJ-1278 has transmitted
since the last automatic identification.

The identification packet consists of an unsequenced I frame, whose data
field is your MYCALL with "/R" appended, and is addressed to the address
set in UNPROTO.
****************************************************************************
@K            Immediate Cmd     Enter CONVERSE mode
Modes:      All

Parameters:
      None

This is an immediate command to enter the converse mode from command
mode.

Typing "K" is the same as typing the "CONVERSE" command.

In Packet and AMTOR modes, once the MFJ-1278 is in Converse mode, all
characters sent to the MFJ-1278 by paKet are transmitted by the radio.
******************************************************************************
@KISS         ON|OFF    OFF     Sets KISS Mode in Packet
Mode:   Packet

Parameters:
      ON  - Operate the MFJ-1278 in KISS mode.
      OFF - Operate the MFJ-1278 in AX25 mode.

KISS mode provides a simple protocol for use  with a host computer system.

It bypasses most of the controls in the MFJ-1278 and allows the host
computer to control the HDLC frames. It is up to the host computer to take
care of the protocol details such as AX25 or whatever protocol is desired.

The most popular KISS Mode application at this time is TCP/IP but this is
not currently supported by paKet.
******************************************************************************
@LCAlls       call      none    Allows selective packet monitoring
Mode:   Packet

Parameters:
     call - up to 8 callsigns separated by commas.


This command works in conjunction with BUDLIST and allows selective
monitoring of other packet stations when you have set MONITOR ON.

The callsigns specified here may be the calls you want to monitor (if
BUDLIST is ON) or they can be the calls you want to ignore when
monitoring (if BUDLIST is OFF).

To clear the list type "%"  or "&" for the callsign.
******************************************************************************
@LCStream     ON|OFF    ON      Allow lower case after STREAMSW
Mode:   Packet

Parameters:
     ON  - The MFJ-1278 translates the character immediately
           following the STREAMSW character to upper case.
     OFF - No translation is performed.

With paKet's multiple Communications windows, you would normally
select a new Stream by selecting the appropriate window. However, if
you do wish to enter the STREAMSW character followed by the desired
Stream identifier, you should enter the stream in upper case.
Therefore it is recommended you leave this option ON, just in case!
******************************************************************************
@LCok         ON|OFF    ON      Allow Lower case to be sent to paKet
Mode:   Packet

Parameters:
    ON  - The MFJ-1278 will send characters to paKet as they are
          received.
    OFF - The MFJ-1278 will translate all lower case characters to
          upper case.

This feature is provided for those users with a terminal which does
not handle lower case characters.

Some operators prefer to use all upper case for one side of the
conversation and lower case on the other side to more easily identify
on the screen who sent what. In paKet the outgoing and incoming text
is displayed in different colours or intensities, so it is
recommended you leave this option ON, and that lower case be used.
******************************************************************************
@LFadd        ON|OFF    OFF     <LF> after sending <CR> in ASCII/Packet
Mode:   ASCII/Packet

Parameters:
     ON  - A <LF> character is added to <CR> on outgoing packets.
     OFF - No <LF> is added.

If a station reports your transmissions overprinting on one line, this
could be set ON temporarily, but it would be better if the other station
could set AUTOLF ON.

Most TNCs are configured to automatically go to a new line whenever a
<CR> is sent.
******************************************************************************
@LFADDAlt     ON|OFF    ON      <LF> after sending <CR> in RTTY
Mode:   RTTY

Parameters:
     ON  - A <LF> character is added after sending <CR> in RTTY.
     OFF - No <LF> is added.

This option is similar to LFADD (for ASCII/Packet) but here the
default is ON because RTTY operation almost always requires a <LF> to
be send along with a <CR>.

If complex RTTY pictures are being sent you might need to turn this
option OFF.
******************************************************************************
@LFIgnore     ON|OFF    OFF     Ignore <LF> in Packet
Mode:   Packet

Parameters:
     ON  - <LF> characters are ignored in Command and Converse modes.
     OFF - <LF> characters are processed.

LFIGNORE is useful if the other station has left LFADD ON and causes
double spacing on your screen.
******************************************************************************
@LIsten       -         I-cmd   Monitor another AMTOR Mode A connection
Mode:   AMTOR

Parameters:
     none

This is an Immediate command used to begin monitoring someone else's
Mode A connection. It will tell the MFJ-1278 to start synchronising
with the desired signal.

Note that as you are not an active participant in the conversation,
you cannot use AMTOR's automatic error correction. So if you are
receiving errors while monitoring, the errors will not be
automatically retried - the data received, including any errors, is
sent to paKet as received.
******************************************************************************
@MAILBOX      ON|OFF    OFF     Enables PMS
Mode:   Packet

Parameters:
     ON  - Mailbox functions are active
     OFF - Mailbox functions are not active

This is a single user device so you should have USER 1 and select
stream A.

The messages will be date and time stamped if DAYTIME is set.

The following commands are valid for the Mailbox:
   K       - Kill all messages addressed to you.
   K nn    - Kill message in slot nn.
   L       - List messages.
   R       - Read all messages addressed to you.
   R nn    - Read message in slot nn.
   S call  - Send a message to that callsign.
   SP call - Send a private message to that callsign.
   B       - Bye (logoff).
   H       - Help
******************************************************************************
@MAll         ON|OFF    ON      Class of packets to be monitored
Mode:   Packet

Parameters:
     ON  - Monitor both "connected" and "unconnected" packets.
     OFF - Monitor only "unconnected" packets.

With MALL OFF you could have a round table "talk" to a group of TNCs with
similar settings. In this case, you would not be connected to any of the
other stations, but could monitor their transmissions. You would probably
have BUDLIST and LCALLS set to avoid monitoring other stations that are
not part of the round table group.

MALL ON is the normal default setting and is useful for "reading the
mail".
******************************************************************************
@MAtch        ON|OFF    ON      Selectively monitor AMTOR Mode B
Mode:   AMTOR

Parameters:
     ON  - Selective monitoring of Mode B FEC transmissions.
     OFF - Normal monitoring.

With MATCH ON, the MFJ-1278 will not start printing a Mode B signal until
the string in MBEGIN is matched.

Similarly, when the string in MEND is matched, monitoring ceases until the
next MBEGIN string is received.
******************************************************************************
@MAXframe     n         4       Maximum number of outstanding packets
Mode:   Packet

Parameters:
      'n' - 1 to 7. This specifies the maximum number of packets that may
            be outstanding (unacknowledged) at any one time.

MAXFRAME also specifies the maximum number of contiguous packets which can
be sent during a transmission.

If throughput is low because of heavy traffic or poor propagation, reduce
MAXFRAME to 2 or 3.

If you are using HF, reduce MAXFRAME to 1.

A relationship between this and PACLEN can improve the efficiency of file
transfers, allowing long bursts on a good link.
******************************************************************************
@MBegin       cccc      <<>>    Display AMTOR Mode B after MB string recd
Mode:   AMTOR

Parameters:
     cccc - A string of up to 15 characters expected in an AMTOR Mode B
            transmission.

This string is used only when MATCH is ON.

When this string is detected, printing of the message will begin.

Refer to the MATCH command for details.
******************************************************************************
@MEnd         cccc      nnnn    Stop AMTOR mode B display after ME string
Mode:   AMTOR

Parameters:
     cccc - A string of up to 15 characters expected in an AMTOR Mode B
            transmission.

This string is used only when MATCH is ON.

When this string is detected, printing of the message will cease.

Refer to the MATCH command for details.
******************************************************************************
@MCOM         ON|OFF    OFF     Monitor (dis)connected packets
Mode:   Packet

Parameters:
     ON  - Connect, Disconnect, UA and DM frames are monitored.
     OFF - Only information frames are monitored.

This command enables monitoring of supervisory frames when MONITOR is
ON.

All control fields are decoded so that possible faults in the link can
be detected. See the protocol section of your manual for more information.
As with other monitor commands the stations monitored are determined by
BUDLIST and LCALLS.
******************************************************************************
@MCon         ON|OFF    ON      Monitor other packets while connected
Mode:   Packet

Parameters:
     ON  - Monitor mode remains active when MFJ-1278 is connected.
     OFF - Monitor mode is disabled while connected.

Enables monitoring of other conversations while your TNC is connected to
another station. Round table conferences can be had using this command.

If set to OFF all other activity on the channel is ignored while you are
connected to a station.
******************************************************************************
@MFilter      n1-n4     none    Eliminate specified chars from packets
Mode:   Packet

Parameters:
     n - Up to 4 characters, each specifiying an ASCII code (0 to 127, or
         0 to $7f) to be filtered from monitored packets.


This feature is useful if you are using a dumb terminal which interprets
control characters as commands, but for paKet it should not be necessary
to filter out any incoming characters.
******************************************************************************
@MHClear      -         I-cmd   Clear MHEARD list
Mode:   Packet

Parameters:
     none

MHCLEAR is an immediate command to clear the MHEARD list.

With this command, you could keep track of monitor channel activity over a
specific period of time, by clearing the list at the start of the period.
******************************************************************************
@MHeard       -         I-cmd   List of packet stations monitored
Mode:   Packet

Parameters:
     none

This is an immediate command to display the list of calls heard since last
time the buffer was cleared (MHCLEAR or RESTART commands, or power-off).

You can either enter this command at the cmd: prompt or you can
select Alt-H in paKet to generate the command for you.

Stations heard via a digipeater are marked with an asterisk (*).

The maximum number of stations monitored in the list is 18 so that only
the last 18 are displayed. If PASSALL in ON logging of stations heard is
disabled.

If date and time are set, entries will be time stamped.
******************************************************************************
@MODe         mo,bd,m   I-cmd   Select operations mode of MFJ-1278
Mode:   All

Parameters:
     mo,bd,m - mo is 2 chars as defined below; bd is desired baud rate;
               m is desired modem as defined in Chapter 4.

This is an immediate command and selects the MFJ-1278's operating mode.
The MODE command is followed by two characters:
Mode Code      Operation Mode     Default Baud rate
   VP          VHF Packet                1200

******************************************************************************
@MNonax25     ON|OFF    OFF     Allow non-AX.25 packet monitoring
Mode:   Packet

Parameters:
     ON  - Monitor all packets including non-AX.25 packets.
     OFF - Inhibit monitoring of non-AX.25 packets.

This command is provided to permit monitoring of packets such as those
associated with TCP/IP, NET/ROM, THENET, etc.
******************************************************************************
@Monitor      ON|OFF    ON      Monitor other stations' packets
Mode:   Packet

Parameters:
     ON  - Monitoring of packet activity is enabled.
     OFF - MOnitoring of packet activity is disabled.

MALL, BUDLIST and LCALLS determine which packets are monitored.

See also MRPT, MSTAMP and HEADERLN for monitoring options.

MCON allows monitoring when connected.
******************************************************************************
@MRpt         ON|OFF    ON      Show digipeaters in monitored packets
Mode:   Packet

Parameters:
     ON  - Shows connected station identifiers and digipeating path.
     OFF - Shows only originator and destination calls.

The MRPT command determines whether monitored packets are displayed with
the digipeat path in the header.

Digipeating stations are shown with an asterisk (*).
******************************************************************************
@MSPeed       nn        20      Sets CW speed
Mode:   CW/MCW

Parameters:
     nn - (5 to 99) specifies the CW sending speed used by the MFJ-1278

Values below 5 WPM are taken to be 5 WPM.

If MSPEED is less than 15 and FARNSWOR is ON the MFJ-1278 uses the
Farnsworth method of transmission where the element (dot and dash) spacing
are equivalent to 15 WPM, but the character spacing of the slower speed is
used.
******************************************************************************
@MStamp       ON|OFF    OFF     Enables time stamping of monitored packets
Mode:   Packet

Parameters:
      ON  - Time stamp on monitored frames.
      OFF - No time stamp on monitored frames.

Enables time stamping of monitored packets if date and time are set.

The date format is determined by the DAYUSA command.

You might like to set HEADERLN ON if you are using time stamping because
of the additional characters in the header.
******************************************************************************
@MULTIfax     ON|OFF    OFF     Enalbes multi level FAX communications
Mode:   FAX

Parameters:
     ON  - The MFJ-1278 is set to transmit and receive FAX in raw data
           format.
     OFF - The MFJ-1278 ius set to transmit and receive FAX in 2 levels
           format.

If MULTIFAX is ON, the MFJ-1278 operates in raw FAX data mode but this
mode requires a special program format that is currently not supported by
paKet.

With the default setting (OFF) the MFJ-1278 will operate in standard 2
level FAX mode and the FAX image may be printed on the MFJ-1278's printer
if PRINTGRA is OFF.
******************************************************************************
@MYAlias      call-n    blank   Specifies alternate digipeater callsign
Mode:   Packet

Parameters:
      call - This is an alternate call sign for use as a digipeater only.

You must still specify your call sign in the MYCALL command.

Specify an alternate callsign or sub-station ID. Use of this command
permits normal HID with MYCALL, but an alternate call for digipeating.
******************************************************************************
@MYcall       call      nocall  Sets your callsign in the MFJ-1278
Mode:   Packet

Parameters:
      call - Your call sign. You may also use a substation ID (SSID)
             (0-15) if you wish.

Example:
      MYCALL VK2DHU       This tells the TNC my call sign.

All transmitted packets will include this callsign, and any connect
requests to this callsign can now be accepted.
******************************************************************************
@MYselcal     ssss      blank   Specifies AMTOR SELCALL
Mode:   AMTOR

Parameters:
     ssss - This is your SELCAL (selective calling code).

Refer to the section "Mode A: Setup" for a discussion on the derivation of
a SELCAL.

The MFJ-1278 will not respond to a Mode A "ARQ" unless MYCALL is set.
******************************************************************************
@NAVMSG       x         ALL     Selectively monitor NAVTEX messages

******************************************************************************
@NAVSTN       xxxxx     ALL     Selectively monitor NAVTEX stations
Mode:   NAVTEX

Parameters:
     ALL   - Monitor all available NAVTEX stations.
     xxxxx - up to 26 letters, each representing the identifying letter of
             the NAVTEX station to be received.

For example if you want to receive stations A, C and P, enter NAVSTN ACP.
Other stations wil not be monitored.
******************************************************************************
@NAVTEX       -         I-cmd   NAVTEX Mode
Mode:   NAVTEX

Parameters:
     none

This is an immediate command that musat be entered at the "a_cmd:" prompt.

NAVTEX is a special form of Mode B (FEC) SITOR that does not output data
to paKet until "ZCZC" and a Preamble are received intact. The Preamble
consists of 2 letters and 2 numerals. The end-of-message is "NNNN".

The first 2 letters of the Preamble define the transmitting station and
the message class; the following 2 numbers form a serial number for the
message.

Currently NAVTEX stations are found on 518 KHz.
******************************************************************************
@NEwmode      ON|OFF    OFF     Determine mode change upon (dis)connection
Mode:   Packet

Parameters:
     ON  - Switch to data transfer mode with CONNECT command;
           Return to Command mode on disconnect.
     OFF - Switch to data transfer mode at time of connection;
           Do not return to Command mode on disconnection.

If ON the MFJ-1278 will switch to whatever CONMODE is set when the
connection is started without waiting for the connection to be
established. If the connection is terminated, or if the request fails, the
TNC will revert to Command mode.

If OFF, the MFJ-1278 will remain in Command Mode until the connection is
established. Then it will switch to the mode specified in CONMODE. The
MFJ-1278 remains in that mode when the connection is terminated.
******************************************************************************
@NOmode       ON|OFF    OFF     Automatically change to Command Mode
Mode:   Packet

Parameters:
      ON  - The NEWMODE function is ignored. The only way to change modes
            is to type CONV, TRANS, or <Ctrl-C>.
      OFF - The TNC will switch in accordance with the setting of NEWMODE.
******************************************************************************
@NUcr         ON|OFF    OFF     Send <NULL>s after <CR>
Mode:   Packet

Parameters:
      ON  - Send <NULL>s after a <CR>.
      OFF - Do not send <NULL>s.

This command specifies whether or not to send <NULL>s after a <CR> is sent
to the computer.

The number of <NULL>s sent is determined by the NULLS command.

Slower terminals or TTY machines sometimes need a short delay after a <CR>
in order to give it time to get the carriage back to the left hand column.
If you were losing some characters at the beginning of a line, you could
use this feature.

This is not a problem with paKet and you should set NUCR OFF.
******************************************************************************
@NULf         ON|OFF    OFF     Send <NULL>s after <LF>
Mode:   Packet

Parameters:
      ON  - Send <NULL>s after a <LF>.
      OFF - Do not send <NULL>s.

This command specifies whether or not to send <NULL>s after a <LF> is sent
to the computer.

The number of <NULL>s sent is determined by the NULLS command.

Slower terminals or TTY machines sometimes need a short delay after a <LF>
in order to give it time to roll the carriage into position for the next
line. If you were losing some characters at the beginning of a line, you
could use this feature.

This is not a problem with paKet and you should set NULF OFF.
******************************************************************************
@NULLS        n         0       Specifies how many <NULL>s are sent
Mode:   Packet

Parameters:
     'n' - 0 to 30 specifies the number of <NULL>s to send after a <CR>
            or <LF>.

Refer to the NUCR and NULF commands for a discussion on the use of <NULL>s.

paKet does not require <NULL>s so you can leave this parameter set to 0.
******************************************************************************
@OMlc         ON|OFF    OFF     Convert AMTOR text received to lower case
Mode:   AMTOR

Parameters:
     ON  - The MFJ-1278 converts all letters (except those echoed) to
           lower case.
     OFF - No conversion is performed.
******************************************************************************
@Paclen       n         128     Maximum packet data length
Mode:   Packet

Parameters:
     'n' - 0 to 255 specifies the maximum size of the data portion of a
           packet.
      0  - this is equivalent to a maximum packet size of 256.

In normal CONVERSE mode, a packet will be sent when you press <CR>.
If you have set Single Line Mode in the Type Ahead window (via the F4
key) paKet will generate a <CR> at the end of each full line and
cause the MFJ-1278 to send a packet at the end of that line.
However a packet is automatically sent by the MFJ-1278 when PACLEN
characters have been received from the paKet program, so the maximum
size of any packet is determined by PACLEN. If you wish, you could
set PACLEN to (say) 20, and the MFJ-1278 would transmit a packet
after 20 characters are received from the program.  This might be
appropriate for an HF link in poor conditions because there would be
greater chance of getting the full packet through without error if it
is a smaller packet. For good links, a larger packet size is better.
For Binary File transfers, paKet will adjust PACLEN automatically.
******************************************************************************
@PACtime      n         10      Time for automatic transmission of packets
Mode:   Packet

Parameters:
      'n'   - 0 to 250 specifies 100ms intervals
      Every - Packets are sent EVERY n * 100 ms.
      After - Packets are sent AFTER n * 100 ms from last entry at keyboard.

Example:
      PACT A 25       Send a packet 2.5 seconds after the last character
                      was received from paKet.
      PACT E 50       Send a packet every 5 seconds even if data is still
                      being received from paKet.

This parameter is always used in Transparent mode and is used in Converse
mode if CPACTIME is ON. If 'n' is 0, the next packet is sent without any
wait time, but in no case will a zero length packet be sent. The timer
only starts when the first character is received.
******************************************************************************
@PARity       n         0       Sets parity for RS-232 serial port
Mode:   Packet

Parameters:
      'n' - 0 to 3 specifies if and how the parity bit is set on data
            flowing between the TNC and the computer.
       0  - No parity
       1  - Odd parity
       2  - No parity
       3  - Even parity

In normal CONVERSE mode, any parity bit is stripped.

In Transparent mode all 8 bits are sent including parity, if any, set.

If no parity and AWLEN 7 then the 8th bit is set to 0 in Transparent
mode.

For paKet please set AWLEN 8 and PARITY 0.
******************************************************************************
@PASs         n         ^V      Character for <PASS> editing character
Mode:   Packet

Parameters:
      'n' - 0 to 127 specifies an ASCII code to be used as the PASS
            character.

This is the ASCII character code which if inserted in a transmission will
allow the next following character to be transmitted as is when normally
it would be interpreted as a command to the TNC. This will allow, for
example, <CR>s to be embedded in the text as well as other TNC control
characters, including the <PASS> character itself.

Example:
      CTEXT I am here somewhere^V<CR>
            Give me a minute or two.<CR>

      If you didn't use the PASS (^V) the <CR> would have been
      interpreted by the TNC as the end of the CTEXT message. With
      the PASS character, the TNC simply added the <CR> into the
      CTEXT message.
******************************************************************************
@PASSAll      ON|OFF    OFF     Display packets with invalid CRC
Mode:   Packet

Parameters:
      ON  - The TNC will accept packets with invalid CRC's.
      OFF - The TNC will only accept packets with valid CRC's.

This would allow some monitoring of data even on a noisy channel,
although paKet would then display all the invalid "garbage" received
by the MFJ-1278.

Normally you would have PASSALL OFF to ensure an error free display.

MHEARD is disabled while PASSALL is ON.
******************************************************************************
@PIXTones     n         abcd    Sets tones for muti-level FAX/SSTV
Mode:   FAX/SSTV

Parameters:
     n   - aaa,bbb,ccc,ddd as follows:
     aaa - value for the White area (default $BF)
     bbb - value for the Light Gray area (default $DE)
     ccc - value for the Dark Gray area (default $05)
     ddd - value for the Black area. (default $00)

Values for PIXTONES determine the shades of gray in a picture. Refer
to the manual for values for the corresponding shades.

The current version of paKet does not support the MFJ-1278's raw data
format.
******************************************************************************
@PKTPix       ON|OFF    OFF     Print packet pictures to printer
Mode:   Packet

Parameters:
     ON  - The MFJ-1278 sends packet data to the MFJ's printer port
     OFF - The MFJ-1278 sends packet data to paKet via the serial port.

With this option ON, all incoming packet data will be directed to the
local printer port and will not be processed by the paKet program.

It could be selected after the connection is established with the other
station, provided you have the MFJ-1278's printer on and ready.

To exit this mode, press Alt-B to send a Break signal to the MFJ-1278.
******************************************************************************
@PRINTGra     ON|OFF    ON      FAX/SSTV graphics to printer or screen
Mode:   FAX/SSTV

Parameters:
     ON  - Print 2-level FAX/SSTV to graphics printer on MFJ-1278.
     OFF - Graphics are sent to the RS-232 port (to paKet).

This feature is useful only where MULTIFAX is OFF.

As paKet does not currently support the MFJ-1278's special graphics
codes, it would be best to leave the option ON and print the graphics
on the MFJ's own printer.
******************************************************************************
@PRinter      ON|OFF    OFF     Turns printer port on or off
Mode:   All
Parameters:
     ON  - Turn ON  the MFJ-1278's parallel printer port.

******************************************************************************
@PRINTTES     -         I-cmd   Printer test
Mode:   All

Parameters:
     none

This is an Immediate command which sends 223 characters, starting
with the ASCII <SPACE> character (value 32 decimal) up to 255
decimal.

Note, no <CR> or <LF> formatting is done so the printer must be
configured for "Auto Newline" or "Line Wrap ON" to ensure all
characters are printed.
******************************************************************************
@QRt          -         I-cmd   Break an AMTOR link (same as R)
Mode:   AMTOR

Parameters:
     none

This is an Immediate command used in AMTOR Mode to:

      a. End a Mode A "ARQ" connection, or

      b. Stop a broadcast in Mode B (FEC) and Mode S (SELCALL).

In either case, the MFJ-1278 returns to standby/receive mode.

Refer also to the R command which does the same thing.
******************************************************************************
@R            -         I-cmd   Break an AMTOR link (same as QRT)
Mode:   AMTOR

Parameters:
     none

This is an Immediate command used in AMTOR Mode to:

      a. End a Mode A "ARQ" connection, or

      b. Stop a broadcast in Mode B (FEC) and Mode S (SELCALL).

In either case, the MFJ-1278 returns to standby/receive mode.

Refer also to the QRT command which does the same thing.
******************************************************************************
@RADio        n         1       Select the radio port on MFJ-1278
Mode:   All

Parameters:
     n - 1 or 2, specifies the radio port to be used.

This command allows selection of the other radio port from paKet.

The MFJ-1278 will remember the last port used so when it is powered
up it will come up on that same port.

Because this command allows you to change ports from within paKet,
you could set up a Script file to automatically switch to the other
radio, connect to a station on that radio, perform a file transfer,
gather mail, etc, then switch back to the original radio.
******************************************************************************
@RANdomcw     ON|OFF    OFF     Random CW code generator
Mode:   CW

Parameters:
     ON  - Generate and send random Morse Code when in CW mode.
     OFF - Random Morse Code is NOT generated.

Useful for helping other stations to practice their Morse receiving,
and for your own practice too, if you turn XMITOK OFF while you are
practicing!

To terminate Random Morse, enter Alt-B (paKet's BREAK command) to
return to Command Mode. Then set RANDOMCW OFF.
******************************************************************************
@RECOnnect    call1-9   I-cmd   Change packet connect path
Mode:   Packet

Parameters:
     call - Callsign of the station to be reconnected to.
            ("call" may include digipeaters)

RECONNECT is an immediate command to change the  path for the current
connection and is usually accompanied by a new path list.

This command may only be used while you are connected to this "call"
in the current stream.

The integrity of any outstanding frames is not assured.
******************************************************************************
@REDispla     n         ^R      Character to redisplay input line
Mode:   All

Parameters:
      'n' - 0 to 127 specifies an ASCII character code to be used as the
            <REDISPLAY> character.

The <REDISPLAY> character will redisplay and allow editing of the current
input line.

You can also use this key to display a packet which has come in while you
were typing, before transmitting your own packet.

This feature is of limited value with paKet because of paKet's Type
Ahead buffer, which minimises the need for <REDISPLAY>
******************************************************************************
@RESET        -         I-cmd   Reset all parms to original defaults
Mode:   All

Parameters:
      None


                     WARNING   WARNING    WARNING

this command.

If you wish to reinitialise the TNC, but retain your own parameters,
use RESTART.
******************************************************************************
@RESptime     n         5       Set minimum ack time for packet
Mode:   Packet

Parameters:
      'n' - 0 to 250 specifies the number of 100ms intervals for delay.

This command sets the minimum delay before an acknowledgement packet is
sent. This will be in addition to any delay set by DWAIT.

When file transfers are being done, occasionally a collision may occur
with an ACK frame. If RESPTIME is set to say 10 then this will be avoided
and an increase in the throughput will result.

A value of 5 to 10 is recommended.
******************************************************************************
@RESTART      -         I-cmd   Reinitialise the MFJ-1278
Mode:   Packet

Parameters:
      None

RESTART is an immediate command to reset the MFJ-1278 but retaining
the user supplied parameters stored in Battery-Backed RAM.

This has the same effect as switching the MFJ-1278's power off then on.

If a complete reinitialisation is required then use RESET, but that will
require you to reenter all your parameters including your MYCALL, etc.
******************************************************************************
@REstore      -         I-cmd   Flush AMTOR xmit buffer and set LTRS
Mode:   AMTOR

Mode:   RTTY/ASCII

Parameters:
     ON  - Invert Mark and Space tones.
     OFF - Normal decoding.

If you are not printing the other station, it could be (s)he is in
the other sideband. If (s)he is printing you OK, you could try
setting RXINVERT ON.
******************************************************************************
@Screenln     n         80      Length of data line sent from MFJ-1278
Mode:   All

Parameters:
     n - 0 to 255, specifying the number of characters to be
         displayed per line on the screen or platen.

This is used to format the display by sending a <CR> <LF> after
SCREENLN characters have been sent. A value of 0 inhibits this
option.

While using paKet, set SCREENLN 0.
******************************************************************************
@SELcall      ssss      I-cmd   Initiate AMTOR Mode L SELCALL
Mode:   AMTOR

Parameters:
     ssss - the four character SELCAL address the Mode L broadcast is
            being sent to.

When this command is issued, the MFJ-1278 is ready to accept text to
transmit. Type CONV or K to enter text transmit mode, then Alt-B and
R to return to Standby/Receive Mode.
******************************************************************************
@SEndpac      n         <CR>    Character that forces a packet to be sent
Mode:   Packet

Parameters:
      'n' - 0 to 127 specifies an ASCII character code to be used as the
            <SENDPAC> character.

The default character is <CR> which means a packet will be sent when you
press the <CR> key. Please leave this set to the default value (<CR>).

You might like to set this to some value you would not normally use if you
decide to set CPACTIME ON in order to send packets at regular intervals
rather than at the end of a line.

However, if paKet's Word Wrap option is ON (refer to the F4 key) it will
generate a <CR> at the end of a full line to save you having to watch for
the end of a line. So, if you change this SENDPAC character to something
else, that Word Wrap feature will insert the <CR> into the data but will
not cause the packet to be sent at the end of the line as expected, but
will result in the receiving station having formatted line lengths.
******************************************************************************
@SERialno     n         0       Serial number for CW Contest mode
Mode:   CW

Parameters:
     n - 0 to 65535, specifying the new starting value of the serial
         number counter.

This feature is useful for CW Contests. If a "#" character is found
in a line of data to be transmitted, the MFJ-1278 will insert the
current value of SERIALNO, then that counter is incremented.

You can enter SERIALNO to specify a new counter value, in which case
the MFJ-1278 will start incrementing from that value.
******************************************************************************
@SETup        n         I-cmd   Set TNC mode and baud rate

@SLotmask     nn        15      Numberf of sides on slottime dice
Mode:   Packet

Parameters:
     nn - 0 to 127, specifying how many "sides are on the slot time dice"

Only three values are likely to be useful. Note the value of SLOTMASK
should be a power of 2 minus 1. So the valid values are:

    0             This disables Slotting.
    1
    3             This should be the default setting.
    7             Only if the channel is busy.
   15             Only if the channel is very busy.
   31             Only if the channel is VERY busy.
   63             Only if the channel is VERY VERY busy.
  127             Only if....

Access to the channel will be equitably distributed among all users if all
are using the same SLOTMASK and DEADTIME values.
******************************************************************************
@SOlf         ON|OFF    ON      Sense only <LF> as AMTOR newline character
Mode:   AMTOR

            <START> character.

<START> is the code to restart data flow from the TNC to paKet after a
<STOP> has been issued.

                       PLEASE DON'T CHANGE THIS

Although START might be set to 0 temporarily during binary file
transfers with Software handshaking, the paKet program expects START to
be <Ctrl/Q> and will not function correctly if you change it.
******************************************************************************
@STatus       -         I-cmd   Diagnostic information
Mode:   AMTOR

Parameters:
     none

@STOp         n         ^S      Character to stop the TNC sending to paKet
Mode:   All

Parameters:
      'n' - 0 to 127 specifies an ASCII character code to be used as the
            <STOP> character.

<STOP> is the code to stop data flow from the TNC to paKet.

                       PLEASE DON'T CHANGE THIS

Although STOP might be set to 0 temporarily during binary file
transfers with Software handshaking, the paKet program expects STOP to
be <Ctrl/S> and will not function correctly if you change it.
******************************************************************************
@STREAMCa     ON|OFF    OFF     Display callsign after <STREAMSW>
Mode:   Packet

Parameters:
     ON  - Callsign of other station is attached to stream ID.
     OFF - Stream ID only is displayed.

The other stations ID is attached to his stream and then the data is
shown after a colon (:) to look like this -

|B :VK2ATM:Hello Tony how is the new program?


For paKet, please leave this option OFF.   paKet has a separate window for
each stream and the window will display the call sign of the connected
station. Setting the option on will interfere with this processing.
******************************************************************************
@STREAMDb     ON|OFF    OFF     Identifies received <STREAMSW> character
Mode:   Packet

Parameters:
     ON  - Double displays the "|" stream character thus: "||".
     OFF - Displays the stream character as a single "|".

It is RECOMMENDED you set this option ON and configure paKet
accordingly.

This can be used to differentiate between incoming stream characters and
those generated by the TNC.

It is important to note that paKet needs to know how this option is set in
your TNC. There is an option in the Configuration Window for the Multi
User options, to tell paKet how to process the <STREAMSW> character. If
you set STREAMDBL ON in the TNC, you must also set the option on in
paKet. This is especially important for binary file transfers.
******************************************************************************
@STReamsw     n         |       Character to identify change of stream
Mode:   Packet

Parameters:
      'n' - 0 to 255 specifies the ASCII character used to change to
            another connection stream.

You must be in Command mode to change streams.

It is suggested you use the default "|" ($7C) character as the STREAMSW
character as this is the default character used on many other TNCs.

If you change this parameter, you must also change that character in
paKet's Multi User Configuration window.

STREAMSW is equivalent to CHSWITCH on some other systems.

@TRACe        ON|OFF    OFF     Display packet data in hexadecimal
Mode:   Packet

Parameters:
      ON  - Activate hexadecimal TRACE function
      OFF - Normal data display

This command allows for protocol debugging. It displays all header and
data in both hexadecimal and ASCII with a byte count and in shifted
ASCII in another column.
******************************************************************************
@Trans        -         I-cmd   Select Transparent Mode for packet
Mode:   Packet

Parameters:
     none

This is an immediate command to put the TNC in transparent mode to allow
transmission of binary data in full 8 bit format.

Transparent mode is used by paKet for its binary file transfers but you
do not need to concern yourself with this because paKet makes the switch
automatically, returning to Converse mode when the file transfer is
completed.
******************************************************************************
@TRFlow       ON|OFF    OFF     Flow control for Transparent Mode
Mode:   Packet

Parameters:
     ON  - Enables software flow control in transparent mode.
     OFF - Disables software flow control in transparent mode.

You should set this parameter OFF.

It is used for software handshaking when receiving a file in
Transparent mode. The paKet program will look after this for you
automatically.

See also TXFLOW, XFLOW, START, STOP.
******************************************************************************
@TRIes        n         none    Display number of "tries"
Mode:   Packet

Parameters:
      'n' - 0 to 15 specifies the current RETRY level on the selected
            input stream.

This command is useful for statistical analysis of path conditions
especially in noisy conditions.

Typing TRIES without an argument the TNC will return the number of
tries if an outstanding unacknowledged frame exists. If no such frame
exists, it returns the number of tries required for the previous ACK.

In plain English, this means that if you think that you are not getting
through, you can interrogate this number, and if it is approaching REtry,
you're about to lose the connection unless perhaps you hedge by resetting
RETRY bigger or zero, or forcing TRIES 0 (not recommended).
******************************************************************************
@TUNE         -         I-cmd   Key PTT for 30 secs for tuning
Mode:   All

Parameters:
     none

Mode:   SSTV

Parameters:
     ON  - Look for horizontal sync in dark areas of the picture.
     OFF - Rely on the other station to maintain correct sync.

If the other station is using an unstable picture source, such as a tape
recorder, the received picture may become skewed or unstable.

This option causes the MFJ-1278 to look for horizontal sync in dark areas,
assumed to be in the picture's edges. However, this may not work with
pictures that contain dark areas in the data area.
******************************************************************************
@TVMode       n         1       Select SSTV format
Mode:   SSTV

Parameters:
     n - 1 to 5, specifying the SSTV format.

******************************************************************************
@TVBreak      n         sabc    Set SSTV brightness and contrast
Mode:   SSTV

Parameters:
     n - sss,aaa,bbb,ccc
         sss  is the Sync (default $42)
         aaa  is the "white to light gray" value (default 28)
         bbb  is the "light gray to dark gray" value (default $2C)
         ccc  is the "dark gray to black" value (default $30)

This command sets the Brightness and Contrast of the picture, setting the
gray levels.
******************************************************************************
@TXdelay      n         30      Delay before sending packet
Mode:   Packet

Parameters:
      'n' - 0 to 120 specifies the number of 10ms intervals to wait before
            commencing the transmission.

The TNC will wait for this time after keying the PTT line before sending
any data.

This is to allow time for relay switching and settling and in synthesised
rigs for the PLL to lock.
******************************************************************************
@TXFlow       ON|OFF    OFF     Flow control for Transparent Mode
Mode:   All

Parameters:
     ON  - Enables software flow control when in transparent mode.
     OFF - Disables software flow control when in transparent mode.

You should set this parameter OFF.

It is used for software handshaking when sending a file in Transparent mode.

See also TRFLOW, XFLOW, XON, XOFF.
******************************************************************************
@TXInvert     ON|OFF    OFF     Invert transmitted tones for RTTY/ASCII
Mode:   RTTY/ASCII

Parameters:
     ON  - Transmitted RTTY/ASCII data are sent inverted.
     OFF - Transmitted RTTY/ASCII data are not inverted.

This command is similar to the TINV command for AMTOR.
******************************************************************************
@TXTmo        n         0       Number of packet timeouts
Mode:   Packet

Parameters:
     n - 0 to 65535, specifying a health counter that registers the
         number of timeout/recovery events that have occurred since the
         MFJ-1278 was powered on.
******************************************************************************
@TXUiframe    ON|OFF    ON      Processes unconnected info in buffer
Mode:   Packet

Parameters:
     ON  - Enable sending UI frames in converse mode.
     OFF - Disable UI frames in converse mode.

This option tells the MFJ-1278 what to do with unconnected information
left in its buffers.

For BBS operation, the option should be OFF.
******************************************************************************
@UNSHIFT      ON|OFF    ON      Unshift upon <SPACE> for RTTY/ASCII
Mode:   Packet

Parameters:
      ON  - Force LTRS case after a space character
      OFF - No change to the existing case.

Because the Baudot alphabet cannot handle upper and lower case, it uses a
special character (LTRS or FIGS) to shift the receiving machine into the
appropriate case before sending the data. However, in less than ideal
conditions some characters may be lost. While the loss of a data character
or two may be acceptable, the received data could become garbled if the
lost character is one of these special characters. For example, the sender
might be sending letters but the receiving machine is still in FIGS mode!

This option forces the MFJ-1278 to shift back to LTRS mode after each
space character. It is assumed most of the data being received is LTRS
characters.
******************************************************************************
@Unproto      call1     CQ      Set address for unconnected packets
Mode:   Packet

Parameters:
     'call' - The call sign to be placed in the TO address field for any

@XMitok       ON|OFF    ON      Enable transmitter
Mode:   Packet

Parameters:
      ON  - The transmitter's PTT line may be switched on.
      OFF - The transmitter's PTT line cannot be activated.

This feature may be most useful for testing as all other functions work
normally, including sending and receiving of data. The only difference is
that when data is sent to the radio, it is not actually transmitted
because the PTT line is not switched on.

It is also useful if you want to leave the system running while you are
absent, but do not want any unattended transmissions.
******************************************************************************
@XOff         n         ^S      Character to stop paKet sending to the TNC
Mode:   All

Parameters:
      'n' - 0 to 127 specifies an ASCII character code to be used as the
            <XOFF> character.

<XOFF> is the ASCII character to stop data flow from paKet to the TNC.


                       PLEASE DON'T CHANGE THIS

Although XOFF might be set to 0 temporarily during binary file
transfers with Software handshaking, the paKet program expects XOFF to
be <Ctrl/S> and will not function correctly if you change it.
******************************************************************************
@XON          n         ^Q      Character to restart after <XOFF>
Mode:   All

Parameters:
      'n' - 0 to 127 specifies an ASCII character code to be used as the
            <XON> character.

<XON> is the ASCII character to restart data flow from paKet to the TNC
after an <XOFF>.

                       PLEASE DON'T CHANGE THIS

Although XON might be set to 0 temporarily during binary file
transfers with Software handshaking, the paKet program expects XON to
be <Ctrl/Q> and will not function correctly if you change it.
