I set the crlf option in kermit and the display works properly.
Here's the problem -> 200+ servers in the field that will triple space when
crlf is set in the emulator.
I have around 15 support/training folks who dial into these systems
constantly from various locations...
So far, I've been able to have our staff connect to SCO OS5, AIX, Caldera,
RedHat and Debian Woody via serial dial-up, telnet, and secure shell using
kermit (Columbia University), ssh, or TERM (Century Software) without
varying the setup of the emulation (kermit and ssh are passthrough, TERM
maps local ttytype to dest ttytype).

Is there a reason that usb is different from serial, telnet and ssh in that
opost is ignored when set by stty?
If so, then I'll have to train everyone to handle it when they encounter a
usb modem.
