I believe you'll also need either 1.5 or 2 stop bits (can't remember
which) and delays (usually 0 bytes) after CR (and probably LF).
Using an ASR33 with 'remote echo' is a bit like trying to talk
on a transatlantic phone line with broken echo cancellation.
Especially if the 100 baud link is being carried over acoustically
coupled modems (remember those?).
