 TINY-2 commands with version 3.0 or 3.1 firmware. 
═COMMAND══════ARG════DEFAULT═══════════DESCRIPTION═══
*
* This file was amended by G4EGH from one created for use with the 
* PAKET (c)1989 programme only. The additions and alterations have
* made this file specific to the Tiny 2 with version 3, or 3.1
* firmware, and the extra information was obtained from PacComm
* publications.
* 
* The above two lines must remain in this file as is. They are used
* by the programme 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. The maximum number
* of lines is determined by the size of the help window - this detailed
* information does not scroll in the help window, and any lines that
* do not fit will be ignored.
*
* Any line in this file beginning with an "*" is treated as a comment
* and is ignored by the PAKET programme.
*
*UPPERCASE CHARACTERS are minimum that will be correctly passed by the TNC.
******************************************************************************
@3rdparty     ON|OFF    ON      Allow/Disallow messages to other than PMS.

 Parameters:
     ON  - Allow messages to be left for other callsigns.
     OFF - Allow messages for PMS call only.

 A limited form of bulletin board system implemented in release 1.1.6+
(25/10/88), not permitted in some countries. It is used in conjunction
with the PMS (Personal Message System), which must be ON for this to
be implemented.
******************************************************************************
@8bitconv     ON|OFF    OFF     Pass or strip high bit in CONVerse mode.

 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.
******************************************************************************
@ABOUT    Not a TNC command !   Information on this help file.

 This help file was originally known as TNC2.HLP, and was supplied on the
distribution disk of the PAKET (c) programme. Alterations and additions
to this file by G4EGH have made it specific to the PacComm Tiny 2, with
firmware version 3, or 3.1. These changes were current as at 23rd July 1993.

 The amendments to this file by G4EGH were obtained from PacCom publications.

If ABOUT was typed, and then F10 pressed, remember to delete the word ABOUT
from the communications window after exiting this help file. The TNC will
not understand ABOUT as a command...!
******************************************************************************
@ACkprior     ON|OFF    ON      Give priority to acknowledgement packets

 Parameters:
     ON  - Enables prioritised acknowledgements
     OFF - Acknowledgements have the same priority as any other packets
           on the channel

 INTRODUCED IN FIRMWARE VERSION 3.1

 When ACKPRIOR is ON, acknowledgements have priority. This means that as your
TNC receives a frame that it must acknowledge ( ACK ), it will immediately
send the ACK if the channel is clear. If other stations are running with
ACKPRIOR ON, they will not access the channel until you have had a chance
to send the ACK, even if they cannot hear your transmissions.

 When OFF, acknowledgements are queued for transmission the same as any
other frames.
******************************************************************************
@ACKTime      0-250     14      Time required to send RR or RNR frame.

 Parameters:
     n=0-250 in 10 mS increments.

 INTRODUCED IN FIRMWARE VERSION 3.1

 ACKTIME specifies the time required to send an RR or RNR response frame
( an acknowledgement ) to an information bearing frame, at the radio port
data rate. This corresponds to about 510 mS at 1200 bps with 8 digipeaters
and about 140 mS at 1200 bps with no digipeaters. The default of 140 mS
( ACKT 14 ) allows for no digipeaters.
******************************************************************************
@ADdrdisp     ON|OFF    ON      Display monitored frame addresses.

 Parameters:
     ON  - Addresses on monitored frames will be displayed.
     OFF - Addresses on monitored frames will not be displayed.

 The ADdrdisp command enables or disables the display of the callsign 
addresses at the beginning of each monitored frame. The command applies
only to the terminal display, not the printer output.

 If the ADdrdisp is ON, a message will be seen, preceded by the callsigns
of the sending and receiving station,  separated by a chevron [ > ]. 
******************************************************************************
@AMonth       ON|OFF    OFF     Display Alphabetic or Numeric date.

 Parameters:
     ON  - Display alphanumeric month in date ie. 29-Nov-89.
     OFF - Display numeric month in date      ie. 29/11/89.

 The above display will only be valid if DAYUSA is OFF.
If DAYUSA is ON and AMONTH is OFF then the numeric display will be
in the format 11/29/89.

 If DAYUSA is ON and AMONTH is ON the display will be Nov-29-89.

 This function implemented in release 1.1.6+ (25/10/88).
******************************************************************************
@AUTOFwd      ON|OFF    OFF     Marks PMS messages for forwarding

 Parameters:
     ON  - PMS messages are automatically marked for forwarding.
     OFF - PMS messages are not marked for forwarding.  

 This command enables automatic MARKING for forwarding of all
messages with a callsign in the @ BBS field ( unless it would cause
messages forwarded from the HOMebbs to forward back to the HOMebbs.)

 This command does not initiate forwarding actions.
******************************************************************************
@AUtolf       ON|OFF    ON      Send Line feed to PAKET after each CR.

 Parameters:
     ON  - A line feed is sent to PAKET after each carriage return.
     OFF - A line feed 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.
******************************************************************************
@AWlen n      7|8       7       Number of data bits per word.

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

 IN FIRMWARE VERSION 3.1 THE DEFAULT SETTING IS 8.

 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 the YAPP protocol which automatically switches into
Transparent mode for the file transfer, so if you use the YAPP Send or
YAPP Receive options, you would not normally need to concern yourself with
this command.
******************************************************************************
@Ax25l2v2     ON|OFF    ON      Select level 1 or 2 of AX25 protocol.

 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      0-180     0       Extra keyup delay (n*0.1 sec).

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

 This value specifies the time a TNC 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 TNC has this command implemented with 10ms increments.
******************************************************************************
@AXHang       0-20      0       Voice Rptr hang time (n*0.1 sec).

 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

 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 E/A   0-250     E0      Send beacon EVERY/AFTER (n*10 sec).

 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      Select backspace erase or (\) for Delete.

 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 TNC 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.
******************************************************************************
@BReak        ON|OFF    ON      Select TNC response to " BREAK " signal.

 The BReak command controls enabling or disabling packet controller
response to the BREAK signal. The BREAK is a " space " condition on the
serial data input line for longer than two character times which can
generated by many computers and terminals.

 Some devices will generate an inadvertent BREAK signal during
initialisation which may force the packet controller into Command mode.
Setting BReak to OFF eliminates this
******************************************************************************
@Btext        text      blank   Text  sent as a beacon (0-120 char).

 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.


 See also the BEACON command.
******************************************************************************
@BUdlist      ON|OFF    OFF     Treat LCALLS as only stations to monitor.

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

 You must set MONITOR ON also. To have MON ON without this being affected
LCALLS must be set to "BLANK".

 Note: in all earlier TNC versions, this affects connected operation as
well as monitoring!
******************************************************************************
@Bye          This command is issued by an over-the-air PMS user.

 When this command is issued from the remote station, the effect is to 
disconnect that user from the PMS          

 There may be a short delay before disconnection occurs. If there is no 
activity on the radio port for 5 minutes, the PMS itself will automatically
initiate a disconnect request.
******************************************************************************
@CALibrate                      Used to calibrate TNC audio to transmitter.

 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".
******************************************************************************
@CANline      0-$7F     $18(^X) Sets character for Cancel-line command.

 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 a <CR> has
been entered you cannot cancel the line. 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       0-$7F     $19(^Y) Sets character for Cancel-packet cmd.

 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 cancelled 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 TNC. Typed
again restores responses from the TNC. So if you type some command
that causes 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     Enable/Disable connect bell.

 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.
******************************************************************************
@CHeck        0-250     30      Connection timer (n*10 sec).

 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.
******************************************************************************
@CHECKV1      ON | OFF  OFF     Enables CHECK timer when using AX25L2V1

 Parameters:
     ON  - Enables CHECKtime timer ( T3 ) when running AX25 Level 2 Version 1
           Protocol.
     OFF - Disables the CHECKtime timer ( T3 ) and requires a manual
           disconnect sequence.

 INTRODUCED IN FIRMWARE VERSION 3.1

 When ON, the CHECK ( T3 ) timer is used to automatically disconnect an 
AX25 Level 2 Version 1 link when the data hasn't flowed for CHECK time.
This will result in an automatic disconnect when packets have not flowed
between this TNC and the remote TNC for CHECKtime. Note that T3 is not
defined for version 1 operation. See CHECK. When OFF, T3 is ignored and
normal version 1 procedures apply.

 Version 1 protocol MAY be more effective on marginal or noisy links, as it
requires a lower overhead than Version 2
******************************************************************************
@CLKadj 'n'   0-65335   0       Real time clock adjust (slows clock).

 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.
******************************************************************************
@CLKSet       ON|OFF    ON      Determines whether TNC accepts clock updates.

 Parameters:
     ON  - The TNC will accept clock updates from the HOMebbs
     OFF - The TNC will not accept clock updates.

 The clock will only be updated if CLKSet is set to " ON ", and 
the HOMebbs supports clock updating. This would occur when the 
home BBS connects to the PMS callsign.

 If the battery backed clock module is fitted, or if advantage is taken
of the computer time updating the TNC time, then it is recommended
that this option is set to " OFF ".
******************************************************************************
@CMdtime      0-250     1       Sets transparent mode timeout.

 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     Enable/Disable connect message.

 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     Enable/Disable disconn after CMSG sent.

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

 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'  0-$7F     $03<^C> Set the COMMAND mode entry character.

 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 YAPP mode 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      CONV|TR   CONV    Sets mode on connect.

 Parameters:
     CONVERS      - Sets automatic entry to converse mode on connect.
     TRANSPARENT  - Sets automatic entry to transparent mode on connect.

 The connection may be the result of a radio connection request or a
keyboard command if NEWMODE is on.

 Take care if you are typing when a radio connection request is received!

 If the controller is already in the correct mode when the connection is
made it will not change.
******************************************************************************
@Connect      Call      none    Connect to a station via optional rptrs.

 Parameters:
      call1 [Via call2,call3...]

 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 digipeater fields in the sequence you wish to use to route your
packets. The brackets are not typed.

 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 connections to your TNC.

 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     Select temporary or permanent connection.

 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     Date/time stamp connect message.

 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 5 will
automatically set this parameter in the TNC when the programme is
started, using the computer's date and time. paKet 6 can do this if 
required ).

Example:
 The DAYTIME format is determined by the DAYUSA command. If CONSTAMP is ON
and DAYUSA OFF then the connect message might appear as follows:
           cmd: C VK2DHU
           cmd: *** CONNECTED to VK2DHU [21/11/89 20:29:31]
******************************************************************************
@CONVers      none              Enter CONV mode from CMD: (Alt is "K")

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

 Single key operation of this command is "K".

 Link connections are not affected and a return to the command mode can be
made by typing in the Command Mode Entry character (default <Ctrl-C>).
******************************************************************************
@CPactime     ON|OFF    OFF     CONVERS mode timed packet dispatch.

 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 carriage return to each 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 available at the end of lines in
the Type Ahead window.
******************************************************************************
@CRAfter      ON|OFF    ON      Carriage return control .

 Parameters:
     ON  - A carriage return is sent after each frame.
     OFF - Monitored frames are displayed without adding a < CR >.

 A carriage return is normally added to the end of each monitored frame.
CRAfter allows the elimination of the < CR > character for proper display of 
some types of frames.
******************************************************************************
@CStatus      none              Display status of all streams.

 An immediate command to show the link status of all eleven 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   Connect message text (120 char).

 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 character (Ctrl/V) and
<CR> is used at end of each line.

 To clear the CTEXT buffer without issuing a RESET command use % or & as
the first character.
******************************************************************************
@CWid         ON|OFF    OFF     Enable/disable CW identification.

 Parameters:
     ON  - Allow CW identification to be sent at regular intervals.
     OFF - No CW identification is sent.

 This function implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@CWIdtext     text       blank  Text up to 32 characters for CWID.

 Text message of up to 32 characters to be sent in MCW if CWID is ON
at a speed set by CWLEN. Implemented in release 1.1.6 of 25/10/88.
******************************************************************************
@CWLen        1 - 9      6      Set CW speed.

 Set the relative CW speed of the CWID text. (9=13 wpm, 6=20 wpm, 3=40 wpm)
Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@DAytime      yymmddhhmm        Set or display date and time of RTC.

 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 5 will generate this command for you automatically when the programme
starts. paKet 6 will generate this command, or not, as desired.

 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      Print date as mm/dd/yy or dd-mm-yy.

 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. See also AMONTH.
******************************************************************************
@DEAdtime     0-250     33      Used to set slot length, See SLOTS

 Parameters:
     n = 0-250 in 10 mS increments.

 INTRODUCED IN FIRMWARE VERSION 3.1

 SLOTS specifies the number of " slots " to choose from when deciding to
access the channel. Each slot is DEADTIME long.
******************************************************************************
@DELete       ON|OFF    OFF     Delete character <BACKSPACE> or <DEL>

 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 REDISPLAY character (default Ctrl-R).
******************************************************************************
@DIGipeat     ON|OFF    ON      Enable/disable digipeating through you.

 Parameters:
     ON  - The TNC will allow digipeating through your call.
     OFF - The TNC 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.
******************************************************************************
@Disconnect   none              Teardown connection path.

 Parameters:
      None. This command is given when it is desired to disconnect from
another station. Usually, the TNC will be in CONVERSE mode. It is necessary
to enter command mode, by entering CONTROL C, after which the disconnect
command may be given. If this command is given in CONVERSE mode, the command
is treated as data, as are all commands when in CONVERSE mode. Consequently,
the other station will receive the command as data, and the path will remain
connected. When the path has been successfully disconnected, the display
*** DISCONNECTED will be given.

 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      A,C,H,I,L,M,T (All,Async,Char,Health,Id,Mon,Timing).

 Parameters:
     none     - Display all current parameters and their values.
     ASYNC    - Display asynchronous port parameters.
     CHARACTE - Display special characters.
     HEALTH   - Display health counters and LED status.
     ID       - Display ident parameters.
     LINK     - Display link parameters.
     MONITOR  - Display monitor parameters.
     TIMING   - Display timing parameters.

 Example:
      DISP A          This displays the asynchronous port parameters.

 The first letter of any of the sub-command parameters is all that is
required.
******************************************************************************
@DWait        0-250     16      Delay for digipeaters (n*10 mSec).

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

 TNC 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.

 The ROSE or NETROM networking when fully implemented will go a long way to
eliminating this problem.

 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).

 NOTE: The better methods of retry timing are the PERSISTENCE or SLOTS
algorithms. If used ( and ALL stations on the channel should use them )
DWait should be set to 0 in the TNC, and in both paKet settings. 
******************************************************************************
@Echo         ON|OFF    ON      Echo typed characters to screen.

 Parameters:
     ON  - Characters received from PAKET are echoed by the TNC.
     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.
******************************************************************************
@EDithdr      n to-call @-call  Redirection of PMS messages.

 Parameters:
     n: message number to be redirected.
     to-call: revised callsign to be placed in the TO location.
     @-call: revised callsign to be placed in the @ BBS location.

 The EDithdr command allows editing of PMS message headers to allow the
re-addressing of messages. Either two or three parameters are required.

 Editing of the BID is not permitted.
******************************************************************************
@EScape       ON|OFF    OFF     Display character for <ESCAPE>

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

 The translation is disabled in transparent mode.
Some terminals interpret the ESC character as a special command prefix
and may alter their displays depending on the character following the
ESC. Setting ESCAPE ON can protect against such alterations.
See also MFILTER for general character stripping rather than translation.
******************************************************************************
@FIrmrnr      ON|OFF    OFF     Prevents frequent polling of busy TNC's.

 Parameters:
     ON  - FIrmrnr is active.
     OFF - FIrmrnr is disabled.

 This command is used to prevent the frequent polling of remote TNC's when
they are busy. Correct operation occurs with remote TNC's having
FIrmrnr set to ON, and with most network nodes.
******************************************************************************
@Flow         ON|OFF    ON      Inhibit output from TNC while typing.

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

 Setting FLOW ON will keep incoming data from interfering with keyboard
entry and make the screen easier to read.

 Type-in flow control is designed to avoid confusing displays where the TNC
can send any received data to the display while you are typing something.
It looks like this:

       TYPED COMincomMANDing data

 When you type " TYPED COMMAND " at the same time as " incoming data "
was received from the TNC.

 With FLOW ON the TNC will hold its data if you have started typing and
will send it when the line is complete.

 If you set FLOW OFF, the TNC will continue to send any data to PAKET, but
PAKET has its own flow control and will allow incoming data to build up in
the buffer until you complete the current line. This may suit you as
PAKET's input buffer is larger than the TNC's buffer (PAKET's buffer is
about 32kB) so there is less chance of filling the buffer and losing data.
******************************************************************************
@FNPms      Callsign            Manually force forward to BBS via node.

 Parameters:
     Call#1 ( Via call#2 ) Where call#1 is node callsign, and call#2
                           is an optional digipeater callsign.
                           ( 23 characters maximum string length ).

 This command causes the PMS to connect to a node or switch, via no more than
one optional digipeater.

 Once this connection is in place, the PMS sends the NODetext string, causing
the node to connect to the desired BBS or PMS station. When the connection
is established, the PMS uploads all messages marked for forwarding.

 If the station connected to by the NODETEXT is the HOMEBBS, the BBS format
will be used, otherwise the PMS will follow the standard format.

 If the FNPms command is used to connect to a station that is not a node,
the NODetext will be sent, but will have no effect at the far end, as the
string will be interpreted as data. After approximately 5 minutes, the
PMS will time out and disconnect. If the station connected to by the NODetext
command string is not a BBS or a PMS capable of receiving PMS messages, or if
a forwarding error occurs, the PMS will automatically disconnect.
******************************************************************************
@FPms       Callsign            Manually force forward to BBS

 Parameters:
     Call#1 ( Via call#2 ) Where call#1 is the callsign of the BBS/PMS
                           station to be connected to, and call#2 is     
                           an optional digipeater callsign.
                           ( 23 characters maximum string length ).

 This command causes the PMS to connect to a BBS/PMS station via no more than
one optional digipeater. When this connection is established, the PMS uploads
all messages marked for forwarding. This command may be used to upload
messages from the PMS to another PMS, or BBS. If the station connected to by
the FPms command is the HOMEBBS, the BBS forwarding format will be used,
otherwise the PMS will follow the standard format.

 If the FPms command is used to connect to a station that is not a BBS or PMS
capable of receiving PMS messages, then automatic disconnection will occur.
This also happens in the event of a forwarding protocol error.
******************************************************************************
@FOrward      n                 Marks PMS messages for auto forwarding.

 Parameters:
     n  = the number of the message to be MARKED for forwarding.

 The PMS does not support automatic forwarding to other BBS ( to reduce 
channel congestion ), but supports manual forwarding,( see FPms, FNPms
commands ), and automatic reverse forwarding. If you have an arrangement with
your local BBS sysop to forward BBS mail to your PMS, then the PMS will 
reverse forward MARKED messages to the local BBS when the BBS connects to 
deliver your mail.

 It is not permissible to mark a bulletin for forwarding in firmware version 3.
******************************************************************************
@FRack        1-15      3       Time in secs to wait for ACK.

 Parameters:
      n = 1 to 15 specifying the time the TNC 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.
******************************************************************************
@FSCreen      ON|OFF    ON      Select format of DISPLAY command.

 Parameters:
     ON  - The DISPLAY command generates four columns.
     OFF - The DISPLAY command generates one column.

 INTRODUCED IN FIRMWARE VERSION 3.1

 FSCreen is an ON/OFF command. When set to ON, TNC settings and statistics are
displayed in a four column format. When set OFF, the information is given
in a single column. All text stored in the TNC will always start in column 1
to ensure that the full text is displayed. An 80 column display is required
if this command is set ON.
****************************************************************************** 
@FUlldup      ON|OFF    OFF     Select simplex or duplex mode.

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

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

 When ON the TNC acknowledges each packet individually.

 It should not be used unless a full duplex (split frequency or crossband)
link is implemented.
******************************************************************************
@GPS          ON|OFF    OFF     Use Global Positioning System Receiver.

 Parameters:
     ON  - The asynchronous port is configured for a GPS.
     OFF - The asynchronous port is configured for a terminal

 INTRODUCED IN FIRMWARE VERSION 3.1

 The GPS command is used to activate GPS mode. It is an ON/OFF command.

 This command configures the packet controller to interface with an NMEA 183
compatible Global Positioning System receiver. When in GPS mode, all normal
TNC commands are inoperative.

 Each $GPGGA data string from a properly configured GPS receiver is
automatically inserted into the Beacon text, Connect text, and SText
( PMS connect text ) fields. This field contains the latitude and longitude
fields as well as other useful information.

 To escape from the GPS mode, the back slash " \ " must be sent over the
asynchronous port.
******************************************************************************
@HEaderln     ON|OFF    OFF     Header and text on separate/same line.

 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     Normal/software mon by STA and CON leds.

 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     Enable/disable ID every 9 mins.

 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 a TNC is used as a dedicated packet digipeater this should be ON
and CONOK OFF.
******************************************************************************
@HOMebbs      Callsign-n        Callsign of your home BBS 

 Callsign - up to six alphanumeric characters.
       n - optional SSID from 0-15.

 This command sets the callsign of the " home BBS " which forwards mail 
to your PMS or which you normally access manually.
******************************************************************************
@Id           none              Force an ID packet.

 Parameters:
      None

 An identification packet is sent only if your digipeater has transmitted
since the last automatic identification.

 HID must be ON for this packet to be sent.
******************************************************************************
@K            Immediate Cmd     Enter CONVERSE mode

 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.

 Link connections are not affected and a return to the command mode can be
made by typing in the Command Mode Entry character.
******************************************************************************
@KIll         n         none    Kill a PMS message number.

 Delete or Kill message number n in the PMS message storage area.
 
 Ensure that " KI" ( in short form ) is typed rather than just " K," because
 " K " alone will put the TNC into CONVERSE mode, after which, all further
input from the keyboard will be sent over the radio, rather than as a command
to the TNC. If this accidentally occurs, type CONTROL C to get back to command
mode !
 
 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@KILONFWD     ON|OFF    ON      Forwarded message deletion.

 Parameters:
     ON  - Messages are deleted after forwarding.
     OFF - Messages are retained after forwarding.
 
 This command selects whether messages which have been marked for
forwarding will be deleted after forwarding has taken place
******************************************************************************
@KISs         ON|OFF    OFF     Select KISS mode for TCP-IP.

 Parameters:
     ON  - Put the TNC in KISS mode.
     OFF - The TNC stays in normal AX25 mode.

 Either operation of this switch must be followed by a RESTART. In the
ON condition the computer must be running the appropriate software.

Implemented in release 1.1.6+ of 25/10/88.

 Once the TNC is set in the " KISS " mode, it may only be set to normal 
mode by EITHER :
     1) Sending the ASCII characters 192  255  192 in that order, 
from the computer to the TNC. ( Press the NUMLOCK key, press and hold
the ALT key, press 192, release the ALT key, press and hold the ALT key 
again press 255, release the ALT key, press and hold the ALT key once 
more, press 192, then release the ALT key. ) The numbers are entered 
on the numeric keypad.
     2) Disconnecting the back-up battery inside the TNC. 
******************************************************************************
@LCAlls       Call 1-8  blank   List of calls to allow (Budlist).

 A list of up to 8 calls with or without substation numbers to be
accepted or rejected according to how BUDLIST is set if MONITOR is on.
To clear the list type LCALLS BLANK.

 Note: in earlier TNC versions, this affects connected operation as well as
monitoring!
******************************************************************************
@LCok         ON|OFF    ON      Lower to upper case conversion.

 Parameters:
     ON  - The TNC will send characters to the computer as they are received.
     OFF - The TNC will translate all lower case characters to upper case.

 If both operators set LCOK to OFF then what each types in lower case
will appear as such and the other's transmission will appear in upper
case. This translation is disabled in transparent mode.

 In PAKET this is best set to ON as the outgoing and incoming text is in
different colours.
******************************************************************************
@LCStream     ON|OFF    ON      Allow stream ID to be lower case.

 Parameters:
     ON  - The TNC will convert lower case entry of stream letter to upper.
     OFF - The TNC will process the character as it is entered.

 Normally the stream identifier must be in upper case or an error message
will be generated.
******************************************************************************
@LFadd        ON|OFF    OFF     Add Line Feed to each Carriage Return sent.

 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.
******************************************************************************
@LFIgnore     ON|OFF    OFF     Filter out Line Feed characters.

 Parameters:
     ON  - LF characters are ignored in Command and Converse modes.
     OFF - LF characters are acted upon in Command and Converse mode.

 LFIGNORE is useful if the other station has left LFADD ON and causes
double spacing on your screen.
******************************************************************************
@List         none              List all messages in the PMS.

 An immediate command to list all the messages held in the
PMS storage area in the TNC even if the computer has been switched off.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@LOGonmsg     ON|OFF    ON      Select PMS log-on message.

 Parameters:
     ON  - The standard PMS log-on message is sent.
     OFF - Only the STExt ( if selected ) is sent.

 This command controls sending of the standard PMS log-on message, and
if set to " ON ", inserts the text " Logged on to ( PMS callsign )
personal message system " after the " *** CONNECTED TO " message, and 
before the STExt inserted by the sysop.
******************************************************************************
@MAll         ON|OFF    ON      Monitor connected and unproto frames.

 Parameters:
     ON  - Monitors both connected and unconnected packet frames.
     OFF - Monitors only unconnected packet frames.

 If MALL is off only UNPROTO packets as determined by LCALLS and BUDLIST
are monitored.
******************************************************************************
@MAXframe     1-7       2       Number of outstanding frames allowed.

 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.
******************************************************************************
@MCOM         ON|OFF    ON      Monitor only data or all frames.

 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    OFF     Monitor other frames while connected.

 Parameters:
     ON  - Monitor mode remains active when TNC is in connected state.
     OFF - Monitor mode is disabled while connected.

 Enables monitoring of other conversations while your TNC is connected to
another station. Even number 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      0-$7F     blank   Up to 4 characters purged from data.

 Specifying up to 4 characters delimited by commas which can be filtered
out of incoming packets.

 To clear the list use MFILTER 00.
******************************************************************************
@MHClear      none              Clear the calls heard list.

 MHCLEAR is an immediate command to clear the MHEARD list if you want to
monitor channel activity over a specific period of time.
******************************************************************************
@MHeard       none              Display calls heard with date/time.

 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.
******************************************************************************
@MIne         none              List 10 recent messages to/from PMS call.

 An immediate command to list the 10 most recent message to or from the
PMS callsign.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@MKiss        none              Immediate entry to KISS mode without RESTART

 INTRODUCED IN FIRMWARE VERSION 3.1

 An immediate command to enter KISS mode without having to follow the command
with a RESTART command.

 GREAT CARE SHOULD BE EXERCISED WHEN USING THIS COMMAND, AS ONCE THE TNC HAS
ENTERED " KISS " MODE, IT WILL NO LONGER RESPOND TO ANY OTHER INPUT. TURNING
THE TNC OFF AND BACK ON AGAIN WILL ALSO BE INEFFECTIVE !

See KISS for further information on how to exit KISS mode.
******************************************************************************
@Monitor      ON|OFF    ON      Monitor mode on. (See BUDLIST,MALL,MCON)

 Monitoring of packet activity is enabled or disabled.

 MALL, BUDLIST and LCALLS determine which packets are monitored.
See also MRPT and MSTAMP.

 MCON allows monitoring when connected.
******************************************************************************
@MRpt         ON|OFF    ON      Display digipeater path.

 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 (*).
******************************************************************************
@MSGHdr       ON|OFF    ON      Selects forwarded message headers.

 Parameters:
     ON  - Forwarded messages will have a message header inserted.
     OFF - Message headers will not be inserted on forwarded messages.

 This command selects whether forwarded messages will have a message
header inserted at the beginning of the message.
******************************************************************************
@MSGRoute     ON|OFF    OFF     BBS routing history storage in PMS.

 Parameters:
     ON  - PMS messages contain the complete BBS routing history.
     OFF - The BBS routing history is NOT stored with the message.

 INTRODUCED IN FIRMWARE VERSION 3.1

 When the BBS connects to deliver to the PMS, it offers the complete routing
history of the message it is forwarding. For some messages that have been
routed via many BBS, a considerable amount of PMS memory is required to store
this information. Setting this command ON will allow the full routing to be
saved in the PMS. Setting the command OFF will allow the FIRST and LAST lines
only of the message routing history to be stored, thereby freeing PMS memory.
******************************************************************************
@MStamp       ON|OFF    OFF     Select time stamping of frames monitored.

 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.
******************************************************************************
@MYAlias      call[-n]  blank   Alternate station identifier.

 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[-n]  NOCALL  Station callsign.

 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.

 BEWARE...!!! The TNC will still initiate connects if you forget to enter
your callsign. Some other stations will respond, although certain BBS
software will immediately disconnect if the calling station callsign
is NOCALL.
******************************************************************************
@MYPcall      call      NOCALL  Callsign for PMS.

 Callsign allocation for PMS. This must be different to the MYCALL, but
you can use a different SSID such as -2 or other number. ie. VK2ATM-2.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@NEwmode      ON|OFF    OFF     Change modes as in TNC-1.

 Parameters:
     ON  - Switch to data transfer with connect command - CMD: on disconnect.
     OFF - Switch to data transfer on connect, but not to CMD: on disconnect.

 If ON the TNC 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 TNC will remain in Command Mode until the connection is
established. Then it will switch to the mode specified in CONMODE.
The TNC remains in that mode when the connection is terminated.
******************************************************************************
@NODetext     TEXT      BLANK   A connect string for PMS forwarding.

 Parameters:
     The text is a valid connect string, limited to one digipeater.

 This connect string is used by the FNPms command to cause the node 
or switch in use to connect to the desired station for message forwarding.
This may be the HOMebbs, or another station.
******************************************************************************
@NOmode       ON|OFF    OFF     Allow/disallow explicit mode change only.

 Parameters:
      ON  - The NEWMODE function is ignored. The only way to change modes
            is to type K (or CONV), TRANS, or <Ctrl-C>.
      OFF - The TNC will switch in accordance with the setting of NEWMODE.
******************************************************************************
@NUcr         ON|OFF    OFF     Select send <NULL>s ($00) after a <CR>.

 Parameters:
      ON  - Send <NULL>s ($00) 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     Select send <NULL>s ($00) after a <LF>.

 Parameters:
      ON  - Send <NULL>s ($00) 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'    0-30      0       Number of nulls to send.

 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.
******************************************************************************
@Paclen       1-255     128     Number of Bytes in a data frame.

 Parameters:
     'n' - 1 to 255 specifies the maximum size of the data portion of a
           packet.
 
  DO NOT USE A PACLEN OF 0 ( 256 ) in the TINY 2, as due to a bug
in the firmware, all flow control fails at this setting, the buffers
overflow, and the TNC crashes.
 
 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 TNC to send a packet at the end of that line.

 However a packet is automatically sent by the TNC when PACLEN
characters have been received from the PAKET programme, so the maximum
size of any packet is determined by PACLEN. If you wish, you could
set PACLEN to (say) 20, and the TNC would transmit a packet after 20
characters are received from the programme.  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 YAPP mode file transfers, PAKET will adjust PACLEN automatically.
******************************************************************************
@PACTime      E|A 0-250 A 10    TRANS mode packet send timer.(n*100ms)

 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'   0-3       3       Parity 0=none,1=odd,2=none,3=even.

 Parameters:
      'n' - 0 to 3 specifies if and how the parity bit is set on data
            flowing between the TNC and the computer.

 IN FIRMWARE VERSION 3.1, THE DEFAULT IS 0.

 In normal CONVERSE mode, any parity bit is stripped.

 In Transparent mode all 8 bits are sent including ( if set ) parity.

 If PARITY 0 and AWLEN 7 then the 8th bit is set to 0.

 For PAKET retain the default settings of AWLEN 8 and PARITY 0.
******************************************************************************
@PASs 'n'     0-$7F     $16 ^V  Char to allow any character to be sent.

 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     Accept only valid CRC frames or all.

 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 TNC.
Logging of callsigns in the MHEARD list is disabled, since they may be
incorrect.

 Normally you would have PASSALL OFF to ensure an error free display.
******************************************************************************
@PErsist 'n'  0-255     127     Set threshold for retry with Persist.

 Parameters:
      'n' - 0 to 255 specifies the threshold for the random number
            generator. 0 gives a low chance of transmitting every
            SLOTTIME, while a higher value increases the chance of a
            packet being sent. 255 means transmit without delay.

 This feature is useful only if other stations are also using PERSIST and
SLOTTIME and it is designed to reduce the number of "collisions" on the
air.

 This CSMA method may be selected with the PPERSIST command.

 DO NOT SET THE PERSIST VALUE LOWER THAN 38 ON FIRMWARE VERSION 3.0, as
Settings lower than 38 totally inhibit the TNC from attempting to access
the channel.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@PIdcheck     ON|OFF    OFF     Monitors PID F0 or all PID's.

 Parameters:
     ON  - Monitors only PID's of F0.
     OFF - Monitors all PID's.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@PMS          ON|OFF    OFF     Set personal message system on/off.

 Parameters:
     ON  - Set personal message system ON and store messages.
     OFF - Set personal message system OFF.

 If the MYPcall is set to say VK2ATM-2 then only connects to that SSID
will be able to leave messages addressed to that call if 3rdparty is OFF
or to any legitimate callsign if ON.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@PPersist     ON|OFF    OFF     Set Persist or Frack retry timing.

 Parameters:
     ON  - Sets retry persistence for retry timing.
     OFF - Sets normal Frack timeout for retries.

 This parameter would normally be OFF unless you have other stations in
your area using the PERSIST/SLOTTIME method.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@Read         n         none    Read n message from PMS storage.

 An immediate command to read back message number n from the Personal
Message System storage in the TNC. Most Tnc's will indicate the presence
of an active message by blinking the STA led. After reading a message it
is wise to KILL 'n' it to avoid it being returned to active status after
24hrs.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@RECOnnect    Call      none    Re-establish link via a new path.

 Parameters:
     Call: Callsign of the station to be reconnected to.

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

 The integrity of any outstanding frames is not assured.
******************************************************************************
@REDispla 'n' 0-$7f     $12(^R) Specify ASCII character for <REDISPLAY>

 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>
******************************************************************************
@REMSysop     ON|OFF    OFF     Allows remote sysop operations.

 Parameters:
     ON  - The MYPcall is allowed sysop privileges over the air.
     OFF - The remote sysop privileges are disabled.

 When the REMSysop is ON, the callsign contained in MYPcall is allowed
to read and kill any message remotely ( over the radio ).
******************************************************************************
@RENUmber     Immediate Cmd     Renumber PMS message numbers

 INTRODUCED IN FIRMWARE VERSION 3.1

 RENUMBER is an immediate command that allows the PMS sysop to renumber the
messages that are currently in the PMS buffer. The messages will be
renumbered, starting at message number 1.
******************************************************************************
@RESET        Immediate Cmd     Reset the TNC to default parameters.



                     WARNING   WARNING    WARNING





 RESET will reinitialise the TNC to its default ROM parameters.

 You will lose all your personalised settings and monitor lists if you type
this command. In addition, with certain firmware versions, you may lose
communication between the computer and the TNC, necessitating altering
the serial port settings in paKet to the default values of the TNC. See
DISPLAY for a method of getting your settings back into the TNC quickly!

 If you wish to reinitialise the TNC, but retain your own parameters,
use RESTART.
******************************************************************************
@RESptime 'n' 0-250     10      Delay for sending an ACK (n*100ms).

 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.

 For PAKET, leave RESP at its default of 10.
******************************************************************************
@RESTART      none              Reset the TNC with user parameters.


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

 This has the same effect as switching the TNC's power off then on.

 If a complete re initialisation is required then use RESET, but that will
require you to re-enter all your parameters including your MYcall, etc.
******************************************************************************
@REtry        0-15      10      Number of retries before disconnect.

 Parameters:
      'n' - 0 to 15 specifies the maximum number of packet retries before
            disconnecting.

 A number of 0 specifies an infinite number of retries.

 The time between retries is determined by the FRACK parameter.
******************************************************************************
@RXblock      ON|OFF    OFF     Format TNC data for computer processing.

 RXBLOCK is designed for formatting data for automated operations such
as bulletin boards. It helps such systems to recognise the difference
between valid data and TNC messages.
******************************************************************************
@SAle         Immediate cmd     TNC vendor information.

 SALE is an immediate command that will display any information that the
vendor of the TNC may have programmed into the firmware.
******************************************************************************     

@Screenln     0-255     80      Sets line length on screen.

 Specifying the number of characters to be displayed per line on the
screen or platen.

 While using PAKET, set SCREENLN 0.
******************************************************************************
@SEND         call      none    Enter a message to call in PMS.

 Send a personal message to callsign for later reading by that station
in the personal message service storage area. This is only possible
if the other station has PMS available and has set it ON with a PMS call
the same as the one you have connected to.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@SEndpac 'n'  0-$7f     $0D(CR) Character to force packet to be sent.

 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.

 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.

 Please leave this set to the default value (<CR>).

 However, if PAKET's Word Wrap option is ON (which is the default, but
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.
******************************************************************************

 Hardware handshaking is preferred, and requires an appropriate RS232 cable
between the computer and the TNC. See the paKet manual for constructional
details of a suitable cable.

******************************************************************************
@SLots        0-127      3      Select probability to transmit.

 Parameters:
     n = 0-127 specifies a number of SLOTS

 INTRODUCED IN FIRMWARE VERSION 3.1

 SLOTS specifies the number of " slots " from which to chose when deciding
to access the channel. For example, The default value of 3 results in there
being three slots, each giving a 33% chance of channel access. Each slot
is DEADTIME long. The SLOT method of channel access is similar to using
the PERSISTENCE algorithm. It is not possible to simultaneously use both
methods of channel access, see TAPR.

 A low SLOT value will result in a better chance of attempting to send data
when the channel is clear, while higher values reduce the probability
that channel access will occur.

 SLOTS and the PERSISTENCE method of retry timing are compared below:

  SLOTS       PPERSISTENCE      PERSISTENCE       PROBABILITY TO TRANSMIT

    1             OFF               255               100%
    2              ON               127                50%
    3              ON                85                33%
    4              ON                63                25%
    5              ON                51                20%

 THE SEQUENCE CONTINUES, AND IT CAN BE SEEN THAT VERY HIGH VALUES OF SLOTS
WILL GIVE VERY LITTLE CHANCE OF CHANNEL ACCESS.

 A typical value on a quiet channel would be 2 or 3, and for a busy channel,
5 to 7 would be appropriate. It should be noted that if low values are used
on a busy channel, the channel access will be noted to be aggressive, and
likely to be commented on by other users !
******************************************************************************
@SLottime 'n' 0-250     10      Specify time interval for PERSIST CSMA

 Parameters:
      'n' - 0 to 250 specifies the time interval before the random number
            generation for PERSIST CSMA operation.

 This parameter would normally not be used unless you have other stations
in your area using the PERSIST/SLOTTIME method.

 Implemented in release 1.1.6+ of 25/10/88
******************************************************************************
@STArt 'n'    0-$7F     $11 ^Q  Character for XON to terminal.

 Parameters:
      'n' - 0 to 127 specifies an ASCII character code to be used as the
            <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 programme expects START to
be <Ctrl/Q> and will not function correctly if you change it.
******************************************************************************
@STATus       none              Query TNC about Conn and Ack status.

 An immediate command to query the status of connection and acknowledge
frames in the TNC. 'C' as in CONNECT will also give the status of the
connection.

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@STExt        TEXT      BLANK   PMS sign-on message

 If there is no STExt, the PMS sign-on message will only be that given
by the LOGonmsg ( if that is set to on ). 

 The STExt can be up to 80 characters long, ending with a < CR >.
******************************************************************************
@STOp         0-$7F     $13 ^S  Character for XOFF to terminal.

 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 programme expects STOP to
be <Ctrl/S> and will not function correctly if you change it.
******************************************************************************
@STREAMCa     ON|OFF    OFF     Show stream call after ID.

 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 programme?

 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.
******************************************************************************
@STREAMDbl    ON|OFF    OFF     Print stream switch char twice (||A).

 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' 0-$FF     $7C "|" Sets stream switch character.

 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 "|" ($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. Note that in paKet 6, the
streamswitch character will need to be specified for each stream, and
should all be set to whatever streamswitch character you use. ( This
facility is of no consequence for the Tiny 2, but is useful for other
manufacturers TNCs.
******************************************************************************
@TAPR         ON|OFF    ON      Selects between SLOTS or PERSISTENCE timing.

 Parameters:
     ON  - SLOTS retry timing will be used.
     OFF - PERSISTENCE retry timing will be used.

 INTRODUCED IN FIRMWARE VERSION 3.1

 This is an ON/OFF command, enabling a selection of EITHER TAPR or PacComm
retry timing.
******************************************************************************
@TIPS      Not a TNC command !  Hints and tips on using paKet and a Tiny 2 !

 This section is intended to give some guidance on some of the problems that
may be encountered. TIPS is NOT a TNC command, it is included so that you
may access some ideas quickly, in the event of problems. When you have read
this section, and you are back at the communication screen, use the backspace
key to delete the word " TIPS " !

 Firstly, STREAMDbl ON. This command must be set ON in the TNC, and in paKet.
If the two do not agree, there is likely to be trouble switching windows,
and " YAPP " transfers will be unreliable. Another reason transfers become
unreliable is if the link is poor. When sending a file using " YAPP ",
the protocol demands that the information leaving the computer is
acknowledged back to the computer within 2 minutes. On a busy link, the
packet joins the back of the queue in the TNC buffer, and the timing starts.
When the packet reaches the other end, the acknowledgement joins the back
of the queue in the other TNC.....You get the idea...?

 Failure to enter remote mode when a user connects. First, check that all
the configuration is correct. Still won't work ? It could simply be that
you last touched the keyboard less than 60 seconds ago. If you have, paKet
assumes you are there, and leaves you to take control with the F3 key.

 Remote users get the prompts, but each input they supply is met with the
response " Incorrect command ". This is likely to be because you have the
ECHO in the TNC set to ON. paKet requires it to be OFF. Setting " ECHO OFF "
in the STARTING AUTO COMMANDS section of paKet's configuration will prevent
this happening.

 The TNC refuses to transmit, and all software settings appear correct, as
does the hardware. This could, ( in firmware version 3 ) be caused by having
a PERSIST value less than 38. ( There is a certain " feature " in the
firmware that causes this.) Another possibility causing this problem is that
the squelch on the radio is set too low, so that it is always open, even when
there is no signal. With the squelch open, and receiver noise reaching the
TNC, transmission will not take place, because the TNC hears noise, and thinks
the channel is busy. It is possible to easily fit an accessory PCB in the TNC
to allow the radio to be run with the squelch open all the time. Marginally
better overall performance results from this modification.

 Another modification that is possible to the TNC is the provision of a real
time battery backed clock. This may not be quite as useful as first thought,
paKet thoughtfully updates the TNC clock whenever the software is started,
or from within the programme when " ALT T " is pressed. However, not all
computer real time clocks are accurate, and if a clock module is installed
in the TNC, it may be undesirable to update it with an incorrect time each
time that paKet is started. paKet 6 gives the option not to update the TNC
clock at startup.

 Setting the number of windows: If you wish to have say 3 streams, set paKet
to 4 windows, named A, B, C, and K. Then, when a user connects to the TNC
PMS, this fact is indicated in the fourth window, although the incoming
message cannot be monitored. paKet will indicate that there is traffic in
window 4, and you can see who has called the TNC PMS. This will stop
mailbox connection messages from being displayed on the current window.

 TNC will not talk to paKet. Try turning the TNC off, and back on again.
If a load of garbage appears, the problem lies within the settings of the
RS232 port. Check the speed, and be aware that the default settings in
some versions of firmware are 7 bit, even parity. These settings would have
appeared if you had given the command RESET, when you meant to give the
command RESTART. RESET loses all the stored settings in the TNC, just as if
you had disconnected the power, and removed the backup battery link !
If nothing at all appears when your power off the TNC, and on again, the
problem could be hardware, like the serial lead, or the port on the computer.
Since paKet will only accept COM1 to COM4, and INT 3 and 4 only, check to see
if your COM card is set to something different.

 One lifesaver is to open a receive text file, and give the command " DISP "
( FSCreen should be set to OFF in firmware version 3.1 ) This file may then
be edited, so that it contains all your personal settings ( Callsigns, texts,
etc..). If you accidentally lose all the settings ( see RESET ) paKet can
send this file to the TNC, and quickly restore things back how they were.
You will first, however, have to get paKet talking to the TNC, some versions
of firmware will give difficulty here, and it will be necessary to
temporarily change the serial port configuration in paKet, probably to 7 bit,
even parity. After communication has been re-established with the TNC, give
the commands AW 8, and PAR 0, after which give the restart command. Then set
paKet's configuration to 8 bits, No parity.

 At this point, the file holding all the set-up data may be sent to the TNC.

 Remember to update the file if you make changes to the TNC.

 Some people like to run the TNC with the monitor ON. Fine, unless you are
running hardware handshaking, and you forget to turn the monitor off before
ending your paKet session. There have been a few instances of the TNC getting
lots of monitored traffic that it cannot pass to the computer, because the
computer is switched off. The TNC gets very unhappy about that, and has been
known ( When the PTT timer link pins are shorted ) to put the radio into
permanent transmit. Your " Buddys " will not be Buddys for long...! paKet can
stop this happening for you, just set " MON OFF " in the " End auto commands "
section of the configuration.

 DO NOT SET THE PACLEN TO 0...!!! In some versions of the firmware, setting
PACLEN to 0 results in the TNC losing all flow control. This means that
when the TNC cannot accept data from the computer, because it's buffers
are full, the TNC fails to tell the computer to stop sending data. Any
further data is then lost. This problem shows up on file transfers, but does
not tend to affect live keyboard traffic, because few operators can type
fast enough...!

 When entering a message in the mailbox, DO NOT put a full stop ( . ) at
the beginning of a line. A " Feature " in certain versions of the firmware
will interpret this as a CONTROL Z  and finish the message...!
******************************************************************************
@TKILlok      ON|OFF    ON      Allow/disallow remote killing of messages.

 Parameters:
     ON  - TRAFFIC messages may be killed by anyone.
     OFF - TRAFFIC messages follow normal rules.

 INTRODUCED IN FIRMWARE VERSION 3.1

 The TKILLOK command allows a user on the radio port to kill an NTS message
in the PMS. The RS232 port is not affected by this command.
******************************************************************************
@TRACe        ON|OFF    OFF     Set hexadecimal trace mode on.

 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        none              Enter transparent mode from CMD:

 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 YAPP mode 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     Disable terminal trans mode flow control.

 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 programme will look after this for you
automatically.

 See also TXFLOW, XFLOW, START, STOP.
******************************************************************************
@TRIes 'n'    0-15      none    Set or display retry counter.

 Parameters:
      'n' - 0 to 15 specifies the current RETRY level on the selected
            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.
******************************************************************************
@TXdelay 'n'  0-120     30      Keying delay for transmitter (n*10ms).

 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.
******************************************************************************
@TXDELAYC     0-120     2       Transmit delay dependent upon radio data rate.

 Parameters:
     n = 0-120 specifying additional transmit delay time.

 INTRODUCED IN FIRMWARE VERSION 3.1

 This command is used to cause an additional transmit delay. Effectively,
the keyup time will be automatically adjusted if the HDLC data rate on the 
radio is altered. This can be useful where the data rate is adjusted
dynamically, allowing the transmit delay to track the optimum setting.

 If the TXDELAYC is set to 0, the TNC will act as if a setting of 1 had
been chosen.
******************************************************************************
@TXFlow       ON|OFF    OFF     Disable TNC trans flow control.

 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.
The PAKET programme will look after this for you automatically.

 See also TRFLOW, XFLOW, XON, XOFF.
******************************************************************************
@TXUIfram     ON|OFF    ON      Enable/disable UI frames in converse.

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

 Implemented in release 1.1.6+ of 25/10/88.
******************************************************************************
@Unproto      call      CQ      Address and path for beacons.

 Parameters:
      'call' - The call sign to be placed in the TO address field for any
               unconnected packets, such as Beacons.

 The 'call' address may include up to 8 digipeaters as well. See the
CONNECT command for details on how to specify digipeaters.
******************************************************************************
@USers        0-10      1       Sets number of streams allowed.

 Parameters:
      'n' - 0 to 10 specifies the maximum number of active simultaneous
            connections that you will accept.

       0  - Allow incoming connection on any free stream.
       1  - Allow incoming connection on stream A only
       2  - Allow incoming connection on streams A & B only.
      etc

 This applies only to incoming connect requests - you may  still initiate
up to 10 connections regardless of the USERS value.
******************************************************************************
@Version      NONE      NONE    The firmware version of the TNC.

 This command causes the firmware version of the TNC to be displayed,
including all the features supported, firmware release date, and
EPROM checksum.
******************************************************************************
@Xflow        ON|OFF    ON      XON/XOFF flow control or hardware.

 Parameters:
     ON  - Software flow control is enabled.
     OFF - Hardware flow control is enabled.

 If you have a full RS-232 cable that permits control of your serial
port via the CTS and RTS lines, then set XFLOW OFF and indicate "HW"
flow control in PAKET.CFG or with the ALT-Z option 6.

 If you don't have a full cable (some "RS-232" cables have only 3 pins
connected), you can still use the system by specifying software
handshaking. Set "SW" flow control in PAKET.CFG and set XFLOW ON.

 Hardware flow control is the preferred method if you have a choice.

 See also TRFLOW, TXFLOW, START, STOP, XON, XOFF.
******************************************************************************
@XMitok       ON|OFF    ON      Allow transmitter to be keyed.

 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'     0-$7F     $13(^S) Character to stop data flow to the TNC

 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 programme expects XOFF to
be <Ctrl/S> and will not function correctly if you change it.
******************************************************************************
@XON 'n'      0-$7F     $11(^Q) Character to start data flow to the TNC

 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 programme expects XON to
be <Ctrl/Q> and will not function correctly if you change it.
