Thanks for this pointer. I'm going to try rewriting my terminal I/O
code, what little of it there is, to use that this morning.

After looking at your invective code a second time (somebody in
#twisted pointed me to it last night) I'm still not entirely sure how
ServerProtocol integrates. It seems like you're mainly just using it
as a sort of container of constants to interpret special keystrokes
(like alt-whatever, or backspace or similar) and in the test cases to
produce such sequences. Is that its main use?

Yep, I think twisted.conch.recvline.RecvLine may be what I'm looking
for. My program needs to respond to keystrokes in some cases, and
allow line editing in others -- message entry, for example.
Thanks again for your help and I'll probably be back here with more
questions at some point.
