General Troubleshooting
Problem: The software cannot find the modem and the modem does not respond to AT commands. (The following comments apply to many other problems as well.)
Solution: The most common error with modems is that the communications software is not configured for the same serial port as the modem. Check which serial port the modem is using. Make sure that the software’s serial port setting matches the modem’s serial port setting.
Problem: The modem takes too long to hang up at the end of a telephone call.
Solution: Your modem may not be receiving the required initialization string, which should include the &C1 setting, from your software.
In your software, make sure you have selected your modem. If not, select it and exit and restart your communications software. If you still have problems, add &C1 to the initialization string, then exit and restart the software. (See Tips for Selecting Setup Options in Chapter 2.)
