I need to go over 100 feet. Looking on the internet shows that RS422 can
go about 4000 feet. I would like a wireless solution but I am also
asking to read about what folks have done with RS232 data from point to
point.

Yes the software is set on both computers. Computer A just gives the
data stream. Computer B is reading the RS232 data and the software on
computer B can be set to check serial ports 1-16.

Thanks for the questions and the answer about the modem.
