XPCOM supports all normal modes of AMTOR operation, including
ARQ, FEC and SELFEC. It also incorporates ARQ and FEC listen
modes.
*Initiating an ARQ Link
To initiate an AMTOR ARQ link use the following steps.
1. Press the ALT A keystroke sequence. If the TNC is in
a different operating mode you will be requested to confirm
the mode change.
2. Enter the SELCAL of the other station and press the return
key. If the link is successful you will enter the Transmit
mode. Send you call and name to the other station.
3. Press the 'END' key, this will send the standard +? sequence
used in AMTOR communications.
4. Use the 'END' key at the end of any transmission to
turn the link back to the other station.
*Dropping an Unsuccessful Link
1. If the link is unsuccessful you should drop the link
as soon as possible as to eliminate unnecessary
intereference to other stations.
2. To drop press the 'HOME' key. This will immediately
drop the link and return the TNC to AMTOR standbt mode.
*Indentifying during an AMTOR contact
XPCOM has a very simple way of adding the call signs of the
stations during an AMTOR contact.
1. Press the F3 key and enter the call of the other station.
2. After the call has been entered it may be imbedded into
the outgoing text by pressing 'ALT I'. This will
place 'Othercall DE Yourcall' (W0AAA DE W0BBB) into
the outgoing text buffer.
*Ending an ARQ Contact
To end an ARQ contact press the F4 function key. This
will send "DROPPING LINK DE YourCall" and also send the
appropriate commands to the TNC.
*FEC Communications
To start an FEC transmission, place the TNC in AMTOR Standby. To
do this, press the 'ALT L' key sequence. If the TNC comes up
in AMTOR Listen mode, press the 'ALT L' sequence again.
To place the TNC in FEC Tranmit
Press the Page Up key to go the transmit mode.
To go to Receive

the CQ sequence as described in the Setup Menu section of this
document. To abort the CQ press any key.
If a station links to you an alarm will sound and the auto CQ will
be aborted.

*FEC Listen ( ALT L )
This set the TNC to the FEC listen operating mode, this is
also refered to as AMTOR standby mode. A good example of
this type of transmission can be found at 8532 kHz LSB. This
is a commercial service that transmits full time FEC. By
pressing ALT L a second time to TNC will be switched into
the ARQ Listen ("chirpcopy") mode.
*FEC Mode ( ALT F )
This places the TNC into the FEC transmit mode. This should
be used for calling CQ prior to ARQ mode operation. Either
define an ASCII CQ file like the one an the disk, or use the
BRAG Text or File functions. You may also use the F5 key to
generate an automatic CQ.
To Exit Transmit press Page Down.
*ARQ Mode ( ALT A )
This places the TNC into the ARQ selective calling mode. A
dialog box will appear on the screen. To select, press the
enter key once and enter the other stations SELCAL.
Terminate the dialog box by pressing the enter key. This
will send the appropriate commands to the TNC.
When in the ARQ mode the change over command "+?" may be
sent by pressing the END key on the keyboard.
To break the link in case of an ERROR press the 'HOME' key.
To Drop the Link at the end of a contact press F4.
To cancel the Selcal window press the 'ESC' key.
*ARQ Listen ( ALT L )
This places the TNC into the "ALIST" or eavesdrop mode of
operation. This mode is also refered to as "chirpcopy".
This allows the user to monitor other ARQ contacts.
Alternately pressing ALT L toggles between the FEC and ARQ
listen modes.
*Navtex
Not Implemented in this Release. Use the appropriate
keyboard commands for this mode of operation. NOTE - AEA
must be in the CMD: Mode to access this function.
*SELCAL Mode
This places the TNC into the SELective FEC mode of
operation normally this mode of operation is used for nets
and round table operation. Enter the station SELCAL in the
dialog box. Press 'ESC' to cancel the dialog box.
