MFJ-1278B MULTI-MODE
The PROfmars command causes the MFJ-1278B to set itself up for MARS operations. The
MFJ-1278B sets the following parameters for MARS operation:
AUTOLF OFF
CCITT OFF
DIDDLE OFF
LFADDALT OFF
LFIGNORE OFF
MARSMODE $01
UNSHIFT OFF
RXLFNOCR ON
PTOver nnn: 0<=nn<=255
Parameters:
nnn Where the n variable equals 0 <=n<=255
The PTOver character designates the Pactor changeover character. The PTOver command
was addded in order to make the MFJ-1278B command set compatible with other Pactor
controllers. This character initiates a control direction change in the Pactor signal.
This character can be varied from 0 to 255 decimal, for computers which may not support the
default. The default is CTRL-Y. A value of 0 disables the Pactor changeover.
PTSend
The PTSend command is basically the same as the U1 Unproto command. Entering PTSend
from the p_cmd: prompt will invoke the 100 baud unproto mode. The PTSend is to make the
MFJ-1278B's Pactor command set compatible with other Pactor controllers.
