Both side modems are Multitech, with exactly the same AT settings.
Trying to dial from A (Redhat) to B (HPUX).
Both A and B can dial to some third modems successfully.
Tried all kinds of speed and gettydefs entries. Modem connection is
made, but instead of the login prompt, I got meaningless characters. Any
carriage return will give one more such character. Used cu and kermit as
the calling program, symptom is the same.

Both modem can be accessed locally with cu or kermit, show settings or
dial out.

How can I make B to allow A to connect and login?

Possible causes:

mismatched parity settings
mismatched computer and modem DTE rate at one end or both.

Both modem has modem speed 28800, and port speed 38400, and I tried
various speed in the gettydefs. Which one is the DTE rate?
Parity is always NONE on both end.

DTE is the Data Terminal Equipment. That is, the serial port. So the DTE
rate is the one between the system and the modem. There are two types of
settings for this: fixed rate and "autobaud" (or variable). And they are
set by the software in the system and by the configuration of the modem. For
error correcting modems, one should always use fixed rate in both the system
and the modem. Port speed should be set as high as the port supports to
allow for data compression by the modems.

If one sets the port, or the modem or both, to variable DTE rate then the
DTE rate will change depending upon DCE (modem to modem) speed reported.

When the modems connect, what is reported exactly?

It says 28800.
I changed the permission of the file /dev/ttyd1a1, which is used by the
inittab entry, to be writable, and the dial-in succeeded.

Ah, I see. Strange that you would get garbage rather than nothing in that
case.

The modem can be set to report a number of things in the CONNECT report sent
to the system. Speed (as you noted) can be reported at DCE but also as DTE
(some modems allow both to be reported, some only report one or the other, I
think). Error correction can be reported as well as compression. It is
sometimes useful to know these things.
