Problem: Modem does not auto-answer.

Solution: Your modem may not be configured to auto- matically answer incoming calls. If you want your fax or data software to answer calls, be sure you have selected this option in your soft- ware.

Problem: You encounter other communications prob- lems with your modem.

Solution: 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 ini- tialization string are sent to the modem each time you start your software and override the settings stored in the modem’s nonvolatile memory.

Problem: You are uncertain about the Data Terminal Ready (DTR) and Data Carrier Detect (DCD) settings referred to in your software manual.

Solution: If your software requires that your faxmodem ignore DTR (which is the faxmodem’s default setting) and you are using the &D2 command in the faxmodem’s initialization string or have stored it in nonvolatile memory, your faxmodem does not work properly. If this is the case, store the &D0 command in nonvolatile memory.

Type: AT &D0 &W &Y0 and press Enter.

Make sure that your faxmodem initialization string does not contain &D2.

If your software requires that your faxmodem follow DTR, the previous considerations apply in reverse. If you are having problems, include &D2 in the faxmodem initialization string.

If your software requires that DCD always be forced ON (which is the faxmodem’s default setting), and you are using the &C1 command in the faxmodem initialization string or have stored it in nonvolatile memory, your faxmodem does not work properly. If this is the case, store the &C0 command in nonvolatile memory.
