MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
MULTIFAX ON/OFF Mode: FAX Default: OFF
Parameters:
ON MFJ-1278B is set to transmit and receive FAX picture in raw data format.
OFF MFJ-1278B is set to transmit and receive FAX picture in 2 levels format.
When MULTIFAX is turned ON, MFJ-1278B is set to transmit and receive multi-level FAX
pictures. FAX Raw data format is sent to the RS-232 port during receiving and raw data is
also expected from the terminal program for MFJ-1278B to transmit multi-level FAX picture.
Also see PIXTONES. Multi-level FAX printing to the MFJ-1278B printer port or printing
to the computer screen is not supported by the MFJ-1278B firmware. A Special terminal
program must be used for this operation for those who wish to write terminal program to
support MULTIFAX, more information is provided in the "FAX Operation" section of this
manual.
When MULTIFAX is OFF, the default setting, MFJ-1278B will operate in standard 2 level
FAX mode. FAX data format is sent to the MFJ-1278B printer port when PRINTGRA is
OFF. IF PRINTGRA is ON MFJ-1278B sends only 2 level data the the RS- 232 port.
Note that when MULTIFAX is turned ON, the PRINTGRA command willl be ignored. This
means that under FAX mode with MULTIFAX turned ON, the MFJ-1278B will start to send
raw data to the terminal regardless of the setting of the PRINTGRA command.
MYCALL call[-n] Mode: Packet Default: NOCALL-0
Parameters:
call Callsign of your MFJ-1278B.
n 0 - 15, an optionally specified sub-station ID (SSID).
This command tells the MFJ-1278B what its callsign is. This callsign will be placed in the
FROM address field for all packets originated by your MFJ-1278B. It will accept frames with
this callsign in the TO field and relay frames with this callsign in the digipeat field.
MYCALL will also be used for identification packets (see HID and ID).
The default callsign must be changed for proper operation of the protocols. There should
never be more than one station with the same callsign (including SSID) on the air at once.
The SSID can be used to distinguish two stations with the same Amateur call. The SSID will
be 0 unless explicitly set to another value.
