PACTOR, precede the callsign of the station with an exclamation point (!) when starting the con-
nection (e.g. PACTOR !DC7XJ).
Monitor Only Mode
The KAM Plus provides you with a method to monitor PACTOR without allowing another station to
link to you. To enter this mode, you must first have the command prompt (cmd:). Type PTLISTEN
then press return. You can now monitor FEC or ARQ PACTOR signals, but your KAM Plus will not
respond to any attempt to link to you. To exit this mode, type [Ctrl-C][X] and the KAM Plus will re-
turn to the Command mode, sending you the cmd: prompt.
PACTOR Directives
While operating your KAM Plus in the PACTOR modes, several directives are available to perform
various functions without returning to the Command mode (cmd:). The directives and their pur-
poses are:
[Ctrl-C][A] Abort a link or abort an attempt to link after the first invalid response code
[Ctrl-C][D] Disconnect
[Ctrl-C][E] Changeover from ISS to IRS (ARQ mode) when transmit buffer is empty.

[Ctrl-C][R] Changeover from ISS to IRS (ARQ mode). Changeover is immediate if data
has not all been transmitted, it stays in the transmit buffer
[Ctrl-C][S] Select the next MARK/SPACE shift (170/425/850/MODEM)
[Ctrl-C][T] Seize the link if IRS (ARQ mode). Enter transmit mode (FEC mode)
[Ctrl-C][X] Disconnect the link (if linked) and return to PACKET
