Be sure your command line contains fewer than 40 characters.
Your modem goes off-hook and seizes the telephone line
when there is an incoming voice call that you want to take
on your telephone.
The modem is configured for auto-answer. Turn off auto-answer
in your software.
Modem does not auto-answer.
Your modem may not be configured to automatically answer
incoming calls. If you want your fax or data software to answer
calls, be sure you have selected this option in your software.
You encounter other communications problems with your
modem.
Check that your communications software has been set up
properly. Recheck the initialization string and dial string specified
in your software manual. Remember that commands in the
initialization string are sent to the modem each time you start your
software and override the settings stored in the modem’s
nonvolatile memory.
On IBM PC-compatible computers, memory-resident (TSR)
programs can cause a variety of problems for some fax software
programs. Try starting up your computer without them. Examples
of TSRs include anti-virus programs, screen savers, and data
protection software.
The modem speaker volume is too low or too high.
You will need to install or move the jumpers on the modem. This
procedure is described in Appendix B.
If the software allows you to control the speaker, make sure the
speaker is enabled and set to a comfortable volume.
If the software does not have speaker settings, add one of the
AT commands listed below to the initialization string:
L1
for low volume
L2
for medium volume
L3
for highest volume
For example, if you want the volume low and the software uses
the initialization string AT &F change it to AT &F L1.
