11.6.3.1 Ending an ARQ PACTOR Contact
When you've finished your "final finals" to the distant station and
both stations are ready to end the PACTOR ARQ contact, you can end
the contact and terminate the link in several different ways:
o Type <CTRL-D> to stop sending after the transmit buffer is empty.
<CTRL-D> breaks the link and returns your PK-900 to Command Mode
in PACTOR Standby. This is the best way to end a PACTOR contact.
o Type <CTRL-F> to stop sending after the transmit buffer is empty,
send your Morse ID and return to PACTOR Standby and Command Mode.
Your PK-900 sends your call sign (in MYCALL) in Morse code, and
then shuts off your transmitter and returns to PACTOR Standby
and Command Mode. This is the best way to end a contact if you
want to identify your station in Morse code as well.
o Wait until all the text has been sent, then type <CTRL-C> to
return to Command Mode, then type "R" to break the link. The
PK-900 will go into the PACTOR Standby mode.
o Type <CTRL-C> to return to Command Mode, then type "R <Enter>
R <Enter>" to break the link immediately! If there are
characters left in the transmit buffer, they will not be sent.
This method should only be used for an emergency shutdown as it
does not send the control signal to the other station that
informs it you are shutting down. As a result, the other station
will continue to send until its internal timer turns it off.
11.6.4 Long Path Contacts
If the station you wish to contact is more than half way around
the world, i.e. a long path station, a special connect command
is used to lengthen the PACTOR timing. In this case, precede the
station's call with the exclamation point:
PTCONN !N7ML <Enter>
If your station doesn't link within a period of time determined
by the ARQTMO command (default 60 seconds), your station will
stop transmitting.
