What are the pros and cons of external vs. internal modems?  If an external plugs into the serial port, does that mean some other device can't be used?
I want a speakerphone to speak to people I call at their house (and I don't like headsets).  There sia 3com external faxmodem pro that comes witha highly-rated speakerphone.  If I had an internal, how can I do the same thing?

Thanks,
Ira Wallin
