Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 272)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
RVFALWAY ON/OFF Mode: Mailbox Default: ON
Parameters:
ON
Initiates forwards and reverse forwards of all forwardable messages.
OFF
Mailbox ignores Forward and NODEforw commands.
The setting of RVFALWAY(s) controls whether the TNC will initiate forward events, via
the FORWARD and NODEFORW commands in the absence of forwardable messages. If
OFF, the TNC will ignore FORWARD and NODEFORW commands entered in the absence
of forwardable messages. When ON, the TNC runs the event for the sole purpose of eliciting
reverse-forwardable messages from the remote BBS.
RXINVERT ON/OFF
Mode: RTTY/ASCII Default: OFF
Setting the RXINVERT command to ON causes the MFJ-1278B to change it's decoding
scheme for Baudot RTTY and ASCII signals. The MFJ-1278B changes the decoding scheme
from the standard low tone used for MARK to the inverted high tone used for MARK.
At times, stations you work may inadvertently be in the wrong sideband mode. If you not
printing him correctly, then try turning RXINVERT ON.
SCREENLN n
Mode: All Default: 80
Parameters:
n 0 - 255, specifying the screen or platen width, in characters, of the terminal.
This value is used to properly format terminal output. A <CR> <LF> sequence is sent to the
terminal at the end of a line in Command and Converse Modes when n characters have been
printed. A value of zero inhibits this action.
If your computer automatically formats output lines, you should set SCREENLN 0 to avoid a
conflict between the two line formats.
SELCALL ssss
Mode: AMTOR Immediate Command)
The SELCALL command initiates a Mode L "SELCALL" broadcast. The ssss is the four
character SELCAL address the broadcast is being sent too.
