Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 247)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
MYcall callsign Mode: Pactor Default: MFJPACTR
The MYCALL command is the same as the MYCALL command used in the Packet mode.
The MYCALL command can take callsigns up to 8 characters in length. The callsign used
must be at least 4 characters in length.
MYALIAS call[-n]
Mode: Packet Default: <blank>
Parameters:
call Alternate identity of your MFJ-1278B.
n 0-15, an optionally specified sub-station ID (SSID).
This command specifies an alternate callsign (in addition to the callsign specified in
MYCALL) for use as a digipeater only.
In some areas, wide coverage digipeaters operators have changed the callsign of their
machine to a shorter and (usually) easier to remember identifier. International Civil Aviation
Organization (ICAO) airport identifiers, sometimes combined with telephone area codes,
have been used.
Use of this command permits HID to identify normally with the MYCALL-specified callsign
yet permit an alternate (alias) repeat-only "callsign."
MYDLCNUM
Mode: Host Default: 0
Set to a non-zero number < 255 (TNCs should start at 1; hosts should start at 254 and go
down). When set to a non-0 value, the addressing procedures for multiplexing TNCs on the
RS-232 port are enabled.
