PORTABLE USB MODEM
• If you have extension phones on the same line as your modem, you or
someone else can interrupt the connection by picking up another phone. If
this is a frequent problem, disconnect the extension phones before using the
modem, or install another phone line especially for the modem.
• Check for loose connections between the modem and the computer and the
telephone jack.
• You might have had a poor connection because of line conditions or the
problem might have originated on the other end of the line. Try again.
• If you were online with an online service, it might have hung up on you
because of lack of activity on your part or because you exceeded your time
limit for the day. Try again.
6.5 The Modem Cannot Connect When Answering
Autoanswer might be disabled. Turn on autoanswer in your data communications
program or send the command ATS0=1 (ATS0=2 if you have Caller ID service) to
make sure your modem is in terminal mode.
6.6 The Modem Doesn’t Work with Caller ID
• 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.
6.7 Fax and Data Software Can’t Run at the Same Time
Communications devices can be accessed by only one application at a time. In
Windows 98, you can have data and fax communication applications open at the
same time, but they cannot use the same modem at the same time.
