E-term2 should be able to keep up with 9600 baud (at least
short bursts). You may be right about the escape sequences.
The pbx we were connected to was designed to talk to a WYZE
terminal, not a pc. Therefore it sent some "weird" codes -
cursor position, etc. Don't count on them all beginning with
esc, either.
Hopefully, the info will be in the manual
(and, hopefully, I will win the lottery - about the same chance)
The manufacturers of the switch may give you some info, but
most likely you will have to find this out by trial and error.
There are a couple of DOS port monitor programs available on
the web. They can keep track of the input and the output
streams, so you can see what's going on. I'm sorry I don't
remember the names.
I think it would be good to rewrite e-term.ex so it sends a line
at a time, rather character by character. You could avoid
echoing the ugly backspace character this way.
