Its a standard setting in most RTTY software, called "auto-cr-cr-lf".

I actually made a web post about it I can link to when needed: https://www.junknet.net/radio/rtty/crlf/

Hi GKs,

Just out of curiosity...

Was it ever historically customary to add some kind of diddle or buffer
between transmission of the CR and LF in RTTY, or is that just a modern
courtesy in some feeds?  I do sometimes wonder if the immediate LF
after the CR would, over time, "wear out" or cause occasional issues
lest a machine's CR mechanism be on the slower end to somehow miss
the LF.

I'm wondering if there's any way to tweak MMTTY to interpret newlines
with a little bit of buffer between the CR and LF since it seems
like it doesn't give my M26 a breather on newlines...haha.

Looking forward to your input.
Thanks and 73,

Jomar
