No to both, but I know what one is.

The "modem" is a leased line NTU (Network Terminating Unit) and is probably
synchronous only. The buttons apply loopback tests (Local or Remote) and
put it in normal (online) mode. If it is sync, it won't work on a PC
com port!

If you are trying to use it as a general purpose modem you are out of luck.
All it will do is connect to a leased line, it is a completely "dumb" device.
The behaviour you describe is about what one would expect.

If the NTU is connected to a leased line and is in "Normal" mode you should find
yourself connected to whatever is at the "other end" of the leased line.

I don' know if this helps?
