It is a modem.

As suggested:

kosmos# cu -l /dev/cuau0 -s 1200
Stale lock on cuau0 PID=3642... overriding.
Connected
at&F
OK
atdt0045*******
NO DIALTONE

The last message can be explained. There is no line connected yet. But this
looks very promising again. What do you exactly mean with ``Oh, hmm, looks
like the clock has an unusual multiplier.'' What kind of multiplier are you
talking about?

How to proceed?

B.t.w. cu looks like a nice tool. I was not aware of its existence.
