USER'S GUIDE
o Don't use this option when retransmitting text, such as ARRL RTTY bulletins re-
ceived from another station – the received text already contains the carriage re-
turns. Thus, enabling "Automatic CR" sends double or triple line feeds which look
very strange to the distant station.
o Many stations using electromechanical teleprinter and Teletype machines habitually
send the traditional line ending sequence of <CR><CR><LF><LTRS> needed to
allow the slower machines to return to the left margin. The double <CR> will pro-
duce a double line feed if you set set ARCRTTY at less then the number of columns
or characters-per-line used by the originating station. The default value of 71 is ac-
ceptable for most received traffic. If you want to be certain that automatic carriage
return is disabled, set ACRRTTY to 255.
o When sending RTTY pictures, you want everything exactly as typed.

sent automatically after a <RETURN> is typed. Use this option when you are hand-typ-
ing text into the transmit buffer and don't want the bother of watching the screen to
see when you come to the end of a line. The same restriction apply to this option as to
the automatic carriage return option described above.
3.4.2.8
Backspace and Delete <DEL>
Use your keyboard's <BACKSPACE> to backspace. Depending on how you've set the
BKONDEL and DELETE parameters, your <BACKSPACE> key may be a "destructive"
backspace key.

from the transmit buffer as well.
3.4.2.9
Escape Functions <ESC>
The echoed ESCAPE character can be either your keyboard's ESCAPE ($1B, ASCII 27)
key, or the "$" dollar sign character ($24, ASCII 36). The default is the ESCAPE key.
This option is provided because some terminals and computer terminal emulator pro-
grams may interpret the ESCAPE character as a special command prefix. These termi-
nals change display functions depending on the characters that follow the ESCAPE key.
o If your computer presents this problem, set ESCAPE to ON.
o See the MFILTER command which lets you strip or filter out any received characters
and prevent them from reaching your computer or terminal.
