I see bad COM ports quite a bit, even with the problem you're describing. Usually its pretty easy to tell; look on the motherboard for 2 identicial chips that have traces running to the COM ports (they'll probably have "232" in the name somewhere). If you see bulges or cracks on either chip then they're bad. Another way to tell is to let the voicemail run for awhile, then turn it off and immediately touch the aforementioned chips; if they're hot they're bad. (Be warned, they could get REALLY hot if they're bad); make sure you're touching the case when you do this so you don't damage something with static.

Just a final update...

I visited the client again, and took with me a StarTech 2 Port 16550 Serial ISA Card (ISA2S550). I disabled the on board COM ports, and set this card to COM 1&2. However, due to IRQ conflicts I was unable to get the modem to work with this card. I simply removed the modem (not like I ever used it).

I just want let everyone know that the StarTech ISA card w/ jumpers works perfectly on a DOS based Corporate Office.

Thanks for all your input!
