Right. Thanks Wayne. So I would think these various approaches that count letters and automatically inject CRLF in the stream, in order to handle the glass RTTY users who never put in a CRLF, need to buffer the incoming baudot codes somehow in order to not miss some of the traffic.
Or not: Losing a character or two during the injected CRLF is not a big deal in the scheme of things. It's sure better than losing a whole bunch of characters while the teletype continually overtypes and bores a hole on the right when no CRLF ever comes!

After a brief 30 year break from Ham radio and RTTY, I got back on-the-air using WA3FRP to find that everyone had moved to software based operations. But before, I moved to the dark side, I did compete in a number of RTTY contests using my Teletype Model 28 ASR with my original Hal ST-6. So, getting the station setup for a 2018 RTTY RU run using my Model 28ASR and my Hal ST-6 has become a top priority.
