[KNOWLEDGE BASE] [MODEMS] 

 MODEM NOT RESPONDING OR ANOTHER PROGRAM MAY BE USING THE MODEM

If the modem says it is not responding or that another program is using the modem, then one of the following is most likely happening:

  • The computer could just need to be restarted

  • If it's an external modem then it may just need to be turned off and back on.

  • The init string going to the modem could be bad and the modem is responding back ERROR instead of the OK the computer is expecting.

  • Fax or voice mail software could be turned on and is not letting other programs use the modem.

  • If it's an external modem then the cable could be unplugged, bad or the modem could be off or have it's power supply unplugged.

  • The modem driver could be installed wrong and need to be reinstalled.

  • The setting for which port the modem is on could be wrong.

  • On old Non-Plug & Play Modems, the modem could have a conflicting IRQ or COM port set.

  • The modem could be physically broken.

  • There isn't actually a modem present on the computer!
