Can someone explain how those fax/modem/voice line switchers work?  Especially
the modem/voice part.  How can a device determine whether to route a phone call
to a modem, or to the telephone, and how does it ring the phone once it has
picked up the phone and determined it was a voice caller?  Also, is it
transparent to the caller on the other end?

I am wondering if it would be practical to buy one of these devices to run a
BBS on a single phone line...Besides the inconvinience of having the line tied
up, would it be possible for voice callers and modem callers to use the same
line hamoniously?

Any info would be appreciated...thanks
