Summary: We have an 'autobaud' getty replacement which does this.

That's not going to be reliable, and is a problem as well with dial in/out
lines (CD must be high to receive if you're using Modem control, but it
isn't with SOME modems until AFTER they send the result code.  Gack).

Yep -- and we fixed it.  The solution is a replacement getty, as you might
guess.  Once installed, the caller hits <return> and the system determines
the baud rate.  The current version requires only one <return> to do this
unless you have a Trailblazer, in which case it might require 2 <returns>

We've resolved this problem ;-)

The autobauder comes with all Microport products we ship, no extra charge.
