PK-900 Gateway Option Supplement
24
In PTCONN, this command accomplishes the same thing as sending the PTOVER
character. The OVER command is useful in Host mode when sending transparent
data (CONMODE TRANS). To change from ISS to IRS, you would normally send the
PTOVER character, but in Transparent mode, the character would be sent as data
and would not change the link direction. The OVER command changes the direc-
tion without the need to change CONMODE to CONV first.
In AMTOR ARQ, this command inserts “+?” into the data stream being sent. If
EAS is ON, the “+?” is echoed to the terminal.
PTList Immediate Command
Mode: PACTOR Host: PN
Parameters:
In PACTOR Listen (and AMTOR LISTEN) modes, monitored connect attempts are now
displayed like this:
>W1AW <C>
The callsigns are shown one per line and are meant to resemble the way the TNC
monitors connect frames in the packet mode. Since neither mode supports iden-
tification within the calling blocks, no source callsign can be shown.
PTRound ON|OFF Default: OFF
Mode: PACTOR Host: Pr
Parameters:
OFF Returns the TNC to the PACTOR-Standby mode after a PTSEND transmission.
ON Returns the TNC to the PACTOR-Listen mode after a PTSEND transmission.
PTROUND facilitates PACTOR “roundtable” conversations with multiple stations
using the PTSEND (FEC) mode as opposed to the Connected mode.
As the unit finishes sending a PTSEND transmission, it normally returns to
PACTOR Standby mode. If PTROUND is ON, the unit returns to PTLIST instead in
order to copy another station’s PACTOR transmission. PTROUND has no effect
when PACTOR connection ends—the unit will always return to PACTOR Standby.
REINIT Immediate Command
Mode: All Host: RI
This is an immediate command that you can invoke to get out of trouble caused
by setting a lot of commands—especially timing parameters—to strange values.
REINIT can be thought of as being halfway between RESTART and RESET. REINIT
re-initializes most of the commands to their default settings, then does a
