***PREAMBLE
WinPack-TF uses a Virtual TNC - what appears to the user as
the TNC responding to TNC2-style commands is, in fact, part
of the software. The available Virtual TNC commands are:-
***POSTAMBLE
Availability of some commands depends on whether you are
using TF firmware, WA8DED firmware or TFEMU.
Most commands can be abbreviated. The minimum abbreviation is
shown in upper case.
For help on a command use ?<command>. Example: ?DISPLAY
***AUTOSSID
Usage:-
AUtoSSID ON or AUtoSSID OFF
Default:-
AUtoSSID OFF
Purpose:-
If AUtoSSID is on then an SSID is added to your callsign if you make
an outgoing connect from a channel on the Terminal. The SSID is the
same as the channel number, so if you make a connection from channel
'2' your callsign will have an SSID of '2', etc. Outgoing connects
from the main WinPack screen will not have an SSID.
***BEACON
Usage:-
Beacon Every n
Beacon After n
n is a number between 0 and 250.
Example:-
Beacon Every 90
Default:-
Beacon Every 0 (disabled)
Purpose:-
Controls how frequently the beacon text (BText) is transmitted.
"Beacon Every" sends BText every n*10 seconds, "Beacon After" sends
BText only after n*10 seconds have passed with no packet activity on
the frequency.
***BTEXT
Usage:-
BText <text>
<text> is from 1 to 80 characters and can contain Winpack tokens.
Examples:-
BText $MYCALL running $VERSION
BText % (this clears BText)
Default:-
No BText set.
Purpose:-
Specifies the text to be sent at the interval specified by Beacon. It
is sent as an unproto frame to the address specified by the Unproto
parameter.
***CHancall
Usage:-
CHancall <callsign>
Example:-
Chancall G8MZX
Purpose:-
To temporarily change the callsign used on a channel. The callsign
will be used until a connection and disconnection has occurred on that
channel, at which point the channel callsign will revert to MYCALL.
***CONNECT
Usage:-
Connect <call> [<call2> <call3>...]
<call2>, <call3> etc. are optional digipeaters.
Examples:-
Connect G4IDE
Connect G8MZX G4GZL
Purpose:-
Initiates a connect request. The result will be either a succesful
connection being obtained, or a LINK FAILURE message.
***CONSTAMP
Usage:-
CONStamp ON or CONStamp OFF
Default:-
CONStamp OFF
Purpose:-
Enables or disables time stamping of the connected and disconnected
messages from the TNC. Please note - this command is not available
with WA8DED firmware.
***CONVERSE
Usage:-
CONVerse
Purpose:-
Put the Virtual TNC back into converse mode if you have used Ctrl_C
to put it into command mode whilst you are connected. CONVerse is
ignored if you aren't connected.
***CTEXT
Usage:-
CText <text>
<text> is from 1 to 80 characters and can contain Winpack tokens.
Examples:-
CText You are connected to a channel on a WinPack terminal.
CText % (this clears CText)
Default:-
CText Welcome to $VERSION. Sorry, no PMS facilities on this channel.
Purpose:-
Specifies the text that will be sent to stations connecting to a
channel on the terminal screen, not to the the main WinPack system.
See also WCText.
***DIGIPEAT
Usage:-
DIGipeat ON or DIGipeat OFF
Default:-
DIGipeat ON
Purpose:-
Controls whether your station will act as a digipeater for traffic
between other packet stations. Please note - this command is not
available when using TFEMU.
***DISCONNECT
Usage:-
Disconnect
Purpose:-
To disconnect a channel on which a connection exists.If there is no
connection on the channel, the command is ignored. The TNC must first
be put in command mode - you can put it in command mode by pressing
Ctrl_C. You can also make a disconnect by using the Disconnect button,
or by selection "Action", "Disconnect" on the main WinPack screen.
***DISPLAY
Usage:-
DISPlay
Purpose:-
Generates a list of all control parameters and their values.
***DWAIT
Usage:-
DWait n
n is a number from 0 to 127.
Example and Default:-
DWait 16
Purpose:-
Specifies the length of time, in units of 10 milliseconds, that the
TNC will wait before transmitting, to avoid collisions with digipeated
packets. Please note - this command is not available with TF
firmware or with TFEMU.
***FRACK
Usage:-
FRack n
n is a number between 1 and 15.
Example and Default:-
FRack 5
Purpose:-
To specify, in seconds, how long the TNC should wait for an
acknowledgement of a frame before it sends the fram again. Please
note - this command is not available when using TFEMU.
***HELP
Usage:-
Help
Purpose:-
To show a list of the available Virtual TNC commands.
***MAXFRAME
Usage:-
MAXframe n
n is a number from 1 to 7.
Example and Default:-
MAXframe 2
Purpose:-
Sets a limit on the number of unacknowledged frames that will be
allowed to be outstanding on a channel at any one time, and also the
maximum number of frames that will ever be sent in one transmission on
a channel.
***MCOM
Usage:-
MCOM ON or MCOM OFF
Default:-
MCOM OFF
Purpose:-
Controls whether supervisory frames will be displayed in monitored
traffic.
***MHCLEAR
Usage:-
MHClear
Purpose:-
Clear the MHeard list - see also MHeard.
***MHEARD
Usage:-
MHeard
Purpose:-
Display a list of stations heard by the TNC. Up to 16 stations will be
displayed. The list shows callsigns and the date and time at which
each station was last heard.
***MONITOR
Usage:-
MONitor ON or MONitor OFF
Default:-
MONitor ON
Purpose:-
Controls whether monitoring of other traffic is enabled or disabled.
***MSTAMP
Usage:-
MStamp ON or MStamp OFF
Purpose:-
Controls whether monitored frames are time and date stamp when they
are displayed. Please note - this command is not available with
WA8DED firmware.
***MYCALL
Usage:-
MYcall <callsign>
Example:-
MYcall G4IDE
Purpose:-
To specify the callsign used by the TNC. If MYcall is changed whilst
connections on other channels are in progess, the callsign being used
on those channels is not affected.
***PACLEN
Usage:-
Paclen n
n is a number from 1 to 256.
Example and Default:-
Paclen 128
Purpose:-
To specify the maximum length of the data portion of any frame sent
by the TNC.
***PERSIST
Usage:-
PErsist n
n is a number from 0 to 255.
Example and Default:-
PErsist 64
Purpose:-
Sets the probability that the TNC will send a queued frame if it finds
the channel is clear. A value of 255 means it will definitely
transmit, a value of 0 means it will never transmit. It is one of the
two persistance timing parameters, the other is SLottime. Please note-
this command is not available with WA8DED firmware or with TFEMU.
***RAW
Usage:-
RAW <command>
RAW <channel><command>
Example:-
RAW L
RAW 0F7
Purpose:-
To send a raw command to the TNC. If the first character of the
command is numeric then it is assumed to be a channel number, if it
is a letter or '@' then the stream you are using is used for the
channel number. DO NOT USE THIS COMMAND UNLESS YOU ARE SURE THAT YOU
KNOW WHAT YOU ARE DOING AND YOU HAVE A GOOD KNOWLEDGE OF THE WA8DED
AND TF2.7b COMMAND SET!!! The command may sometimes result in the
response from the TNC appearing twice on the screen - this is
unavoidable.
***RESPTIME
Usage:-
RESPtime n
n is a number from 0 to 255.
Example and default:-
RESPtime 150
Purpose:-
To specify the delay, in units of 10 milliseconds, between a frame
being received and the acknowledgement being sent. The idea is to
prevent collisions between the acknowledgement and another frame from
the sending station. Please note - this command is not available when
using TFEMU.
***RPS
Usage:-
RPS
Purpose:-
Returns the number of times that the TNC goes round its internal cycle
in one second.(Rounds Per Second). It is a comparitive measure of TNC
performance. Please note - this command is not available with WA8DED
firmware or with TFEMU.
***SETTIME
Usage:-
SETtime
Purpose:-
Sets the TNC's internal time and date to the PC's time and date. The
TNC uses the time and date for time stamping connections and monitored
frames. SETtime is called automatically during TNC initialisation. See
also CONStamp and MStamp. Please note - this command is not available
with WA8DED firmware.
***SLOTTIME
Usage:-
SLottime n
n is a number from 0 to 255.
Example and Default:-
SLottime 100
Purpose:-
To set the frequency, in units of 1 millisecond, at which random
numbers will be generated to determine if a queued frame will be
transmitted if the channel is clear. It is one of the two persistance
timing parameters, the other is PErsist. Please note - this command
is not available with WA8DED firmware or with TFEMU.
***TRIES
Usage:-
TRIes n
n is a number from 0 to 15.
Example and Default:-
TRIes 10
Purpose:-
Specifies how many times the TNC will retry to send a frame before it
gives up. Please note - this command is not available when using
TFEMU.
***TXDELAY
Usage:-
TXDelay n
n is a number from 1 to 500.
Example and Default:-
TXDelay 30
Purpose:-
Specifies the delay, in units of 10 milliseconds (but see NOTE),
between the push-to-talk being keyed and data being sent, to allow
the rig to stabilise on transmit.
I have been told that the SYMEK TNC3S TNC, which supports a version of
TF, uses a unit of one millisecond for the TXDelay setting, which is
why the upper limit of 500 is so high! The normal versions of TF and
WA8DED will not accept a value above 127.
Please note - this command is not available when using TFEMU.
***UNPROTO
Usage:-
Unproto <call> [<call2> <call3>...]
<call2>, <call3> etc. are optional digipeaters.
Examples:-
Unproto GB7IDE
Unproto GB7OPC G8MZX
Default:-
Unproto CQ
Purpose:-
Specifies the address and optional digipeater callsigns to which
unproto transmissions will be sent.
***USERS
Usage:-
USers n
n is a number from 0 to the maximum number of channels available on
the TNC.
Example:-
USers 2
Default:-
The maximum number of channels available.
Purpose:-
To set the maximum number of simultaneous incoming connections allowed
by the TNC. It does not restrict the number of outgoing connections
that you can make.
***VERSION
Usage:-
Version
Purpose:-
Returns the version of the firmware being used. Please note - this
command is not available with WA8DED firmware, and some versions of TF
may return the AX25 version being used (2) not the the firmware
version.
***WCTEXT
Usage:-
WCText <text>
<text> is from 1 to 80 characters and can contain Winpack tokens.
Examples:-
WCText You are connected to a WinPack system.
WCText % (this clears WCText)
Default:-
Welcome to $VERSION. Send /h for help...
Purpose:-
Specifies the text that will be sent to stations connecting to the
main WinPack system (channel 1 on the TNC). See also CText.
***XMITOK
Usage:-
XMitok ON or XMitok OFF
Purpose:-
Specifies whether the TNC is allowed to transmit. Please note - this
command is not available when using TFEMU.
