• Your computer and the remote computer might be set to different word lengths, stop bits, or
parities. If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your
communication software.
• You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call
again; you might get a better connection the second time.
• 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 &V1 command to display information about the last connection, making a screen
print of the connection statistics, and checking for parameters that might be unacceptable.

• Caller ID information is transmitted between the first and second rings, so if autoanswer is
turned off (S0=0) or if the modem is set to answer after only one ring (S0=1), the modem will not
receive Caller ID information. Check your initialization string, and if necessary change it to set the
modem to answer after the second ring (S0=2).
• Make sure that you have Caller ID service from your telephone company.

• 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 datacomm software, 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 applications open at the
same time, but they cannot use the same modem at the same time.
