At speeds above 2400 bps, the remote modem might not use the
same transmission or error correction standards as your modem.
Try connecting at a slower speed or disabling error correction.
(With no error correction, however, line noise can cause garbage
characters.)

Try entering the L8 (List Online Diagnostics) command in online
mode, making a screen print of the diagnostics listing, and check-
ing for parameters that may be unacceptable (number of retrains,
round trip delay, etc.).
Fax and Data Programs Can’t Run at the Same Time
4
Communications devices can be accessed by only one application at a
time. Under DOS or Windows 3.1x, you can run either your fax soft-
ware or your datacomm software, but not both at the same time,
unless you have a special communication device management ap-
plication. In Windows 95, 98, and NT 4.0, you can have separate
data and fax communication applications open at the same time,
but they cannot use the same modem at the same time.
