I received a bug report today concerning tcpser (the
Linux/Unix/Windows/MacOS modem emulator) and numeric response codes.
https://github.com/go4retro/tcpser/issues/31
I knew long ago that not all codes and commands were common/consistent
among modem manufacturers, but I guess I didn't realize even response
codes differed quite a bit. After receiving the bug report, I did a bit
of research, and found, for instance, CONNECT 19200 differs:

I have two questions for the group, if folks can assist:
* Since I purport to be Hayes compatible, I should use the Hayes code
when available, but the reference above does not go above 38400 bps.
Did Hayes make a modem that went faster (DTE speed?) and if so, can I
get a scan of the manual to ensure the codes I am using are the best ones?
* Any other modem manufacturers anyone is aware of, with manuals I can
check.
