MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

FAXNEG ON/OFF Mode: FAX Default: OFF

Parameters:

ON Reverses the FAX image on screen..i.e. black to white

OFF Disables FAX image reversal. Normal operation.

Setting FAXNEG ON causes the MFJ-1278B to invert the screen image. This means the white areas of the FAX pictures will be black, and the black areas to be white. The synchronization bar is not inverted.

FAXREV ON/OFF Mode: FAX Default: OFF

When FAXREV is turned ON, the MFJ-1278B will invert all received FAX data including synchronization bars. It is analogous to RXINVERT as used by RTTY/ASCII modes.

FEC Mode: AMTOR Immediate Command

FEC immediately causes the MFJ-1278B to start broadcasting with the AMTOR mode B,Forward Error Correction (FEC) protocol.

When the FEC command is issued, the MFJ-1278B keys the transmitter and is immediately ready to accept text to transmit. Type K or CONV to enter the text transmit mode. When you're done transmitting, enter CTL-C and type R to release the transmitter and return the MFJ-1278B to standby/receive.

FIRMRNR ON/OFF Mode: Packet Default: OFF

FIRMRNR controls the handling of busy states by the MFJ-1278B. Setting FIRMRNR ON improves channel efficiency, but is incompatible with earlier TNC-2 releases. The incompatibility is a result of vague protocol specifications.

FIRMRNR should be always be set ON when conversing with network nodes, for example, NET/ROM. In other cases, it is recommended that FIRMRNR be left OFF unless you can be assured the other TNC you are connected to supports FIRMRNR.
