Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 233)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
LFADD ON|OFF Mode: ASCII/Packet Default: OFF
When LFADD is ON and the ASCII or Packet mode is selected, MFJ-1278 will append an
ASCII line feed character, $0A, to the transmission immediately after a carriage return is
sent.
LFADD should usually be switched OFF as the vast majority of TNCs (including the MFJ-
1278B) are configured to automatically go to a new line whenever a carriage return is
printed.

LFADDALT ON/OFF
Mode: RTTY Default: ON
LFADDALT is very similar to the LFADD command above. However this command
applies ONLY to Baudot RTTY mode.
Baudot RTTY operation almost always requires that a line feed be sent along with a carriage
return. When LFADDALT is ON the MFJ-1278B will automatically insert the Baudot line
feed whenever the user sends a carriage return.
There is one case where line feeds should not be automatically transmitted, that is when
sending complex radio teletype pictures.

LFIGNORE ON/OFF
Mode: Packet Default: OFF
Parameters:
ON
MFJ-1278B will ignore <LF> characters.
OFF
MFJ-1278B will respond to <LF> characters.
This command controls whether MFJ-1278B responds to ASCII Lind Feed (<LF> $OA)
characters or ignores them in command and converse modes.
When turned on, line feeds are totally ignored except in transparent mode.
