Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 188)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
BKONDEL ON/OFF Mode: Packet Default: ON
Parameters:
ON
The sequence <BACKSPACE> <SPACE> <BACKSPACE> is echoed when a
character is deleted from the input line.
OFF
The <BACKSLASH> character (\) is echoed when a character is deleted.
This command determines the way the display is updated to reflect a character deletion in
Command Mode or Converse Mode.
The <BACKSPACE> <SPACE> <BACKSPACE> sequence will properly update the screen
of a video display. If you have a video display terminal or computer, you should set
BKONDEL ON.
The <BACKSPACE> <SPACE> <BACKSPACE> sequence on a printing terminal would
result in overtyped text. If you have a paper-output display, or if your terminal does not
respond to the <BACKSPACE> character (<CTRL-H>), you should set BKONDEL OFF.
The MFJ-1278B will type a <BACKSLASH> for each character you delete. You can display
the corrected input line by typing the redisplay-line character, which is set by the command
REDISPLA.
