Testing modems

You can use qtalk to test your modem.

  1. Make sure the modem is plugged into the phone line.
  2. Use the stty command to set the modem's baud rate. For example, to set the speed of the modem on /dev/ser1 to 57600 (56K modems use this speed), type:
    stty baud=57600 < /dev/ser1
  3. Type qtalk -m device, where device is the name of the serial port (e.g., /dev/ser1).
  4. Type at. The modem should reply OK.

For more information, see the entry for qtalk in the Utilities Reference.
