Modem Cannot Connect When Answering

Chapter 5 – Troubleshooting

●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.

●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 in terminal mode.

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 does 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.

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 2003 and higher, you can have data and fax communication applications open at the same time, but they cannot use the same modem at the same time.
