George,
  To the uninitiated (me), what is a zero crossing detector.
   I'm very interested in receiving wefax for our upcoming Bermuda trip.
I've picked up a Sangean 909 and was given a laptop with JVComm Wefax and a
connecting cord for the sound card. Then I stumbled on a real deal for the
Coretex Wefax 95 program that goes into the serial port. Unfortunately, I've
been too busy (and in my midwinter doldrums) to get to try the Coretex yet.
I wasn't successful with the JVComm, but only tried twice.
Regards,
Brian
