The same problem exists with the MultiTech, 224EH series. I thought that
the level 5 MNP had something to do with it, but have since found that it
doesn't. I noticed that when the modem & cpu start "yelling" at each other,
I can sometimes put a stop to it by dropping the CTS signal from the 3B1.
This is connected to the RTS on the modem. This doesn't always work though.

As with your telebit, the 224EH uses the Hayes command set. I set up the
Devices file to show that tty001 was a hayes protocol, but that only handles
the outbound traffic. I am boggled at this point.
