Or for programmed output, you'd (ok, *I* would ;-) program a delay to allow
for the flyback to complete after the line feed which IIRC could be done during
flyback, since it didn't print anything. But I think we had flexowriters before
we had KSR33s. At least I was personally introduced to flexowriters first.

What I am trying to remember is how the Friden flexowriter that was connected
to the LGP-30 I once coded for worked re CR/LF. It definitely had a moving carriage
and moved like a typewriter, but ISTR that one key would do the CRLF. But there was
more than one model, and I suspect there was one that had separate CR/LF codes/functions.
Maybe one we used with a PDP-8 later ;-)
