[RTTY] CRLF ?

CRLF is carriage return and line feed. In the old teleprinter days both
characters had to be sent to cause the print head to be aligned at the start
of a new line, that is carriage return to move to the start of line and line
feed to feed the paper down one line.

In the world of today a CR will do that on the screen so it is no longer
possible to overwrite a line or cause a line feed in a middle of a line or
miss them altogether and get a black box of ink at the end of the line.

2Tone on sending will always include a shift character at the start of a new
line. Sometimes the CRLF can corrupt to a figs/ltrs shift hence it forces a
shift to be sent before the next displayable character. Additionally on
receive 2Tone only needs a CR to cause a new line. It ignores LF characters.
It also removes multiple new lines to avoid someone sending lots in
succession and forcing wanted data off the screen.

N1MM+ and most (all?) logging programs will also force a new line when the
end of the DI window is reached.

Am enjoying the thread regarding Decoder Performance, but you lost me on the
term CRLF. Is that anything other then when constructing Macro, just hitting
the Return Key ??
