XPCOM Version 1.4 Page : 4-1
AMTOR Operation
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, send your call
and name to the other station. If the call sign of the
station has been entered using the F2 function key, the
SELCAL field will have a default Selcal.
Turning the Link Over
1. The 'Page Down' key will send the standard "+?"
sequence used in AMTOR communications.
2. Or use the 'END' key at the end of any transmission to
turn the link back to the other station. The definition
of the end key is user definable, see operating
parameters screen in the setup menu.
To Drop an Unsuccessful Link
1. If the link is unsuccessful you should drop the link
as soon as possible as to eliminate unnecessary
interference to other stations.
2. To drop press the 'HOME' key. This will immediately
drop the link and return the TNC to AMTOR standby mode.
Identifying 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 F2 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. The Alt-I sequence is user
definable see Ident Text in the operating parameters
screen located in the Setup Menu.

The END key is also defined within the operating
parameters and can be used for passing the link back to
the other station.
Ending an ARQ Contact
1. 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. The F4 sequence is user
definable see Drop Link Text in the operating parameters
screen located in the Setup Menu.
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 Transmit
Press the Page Up key to go the transmit mode.
To go to Receive
Press the Page Down Key.
Calling CQ for an ARQ Link
To call an automatic CQ press the F5 function key. This
will start 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.
TMAIL Operation
XPCOM Version 1.4 and above now supports TMAIL for those AEA
controllers that have the mailbox option. The TMAIL status is shown
in the center status bar. To change the state of TMAIL (ON or OFF),
click on the status bar or press Alt-J.
