What to do if I encounter communications problems with my Hayes Modem?
If you're encountering communication problems with your Hayes Modem, check that your communications software has been set up properly. Recheck the initialization string and dial string specified in your software manual. Also, memory-resident programs can cause a variety of problems, so try starting up your computer without them.

If your telephone service includes Call Waiting, turn it off if possible before making modem calls.

Ensure the software’s COM port setting matches the modem’s COM port setting. Also, COM port resources may be in use by another device. Make sure that the COM port resources used by the modem are not being used by any other device, such as a sound card. In terminal mode, type AT at the beginning of the command line. Ensure your modem is not in data mode when you type the command. Use the escape character sequence to switch to terminal mode. If you typed a command but did not receive an OK response from your modem, the E0 and Q1 commands may be in effect, disabling echo and responses. Verify this with the &V command.
