Fax and Data Software Can't Run at the Same Time

Communication devices can be accessed by only one application at a time. Under
DOS or Windows 3.1x, you can run either your fax software or your data
communications program, but not both at the same time, unless you have a
special communication device management application. In Windows 95, 98, and NT
4.0, you can have data and fax communication programs open at the same time,
but they cannot use the same modem at the same time.
