I have a Compaq that I am parting out here and I am trying to use the modem in my other
PC. Plug and play doesn't detect it at all in my other PC but in the compaq it comes up
"UNKNOWN DEVICE". I can add it in add new hardware but it doesn't work properly.

I am really broke so I would prefer to get it to work rather than go out and buy one.

The modem needs to be caller ID compatible as well and I have bought a lot of crap out there that doesn't do too well with caller ID.
