Window Errors
Modem does not exist, is not plugged in or is out of service

• Go to Start then Settings and Control Panel

• Double click Modems

• Click on Diagnostics

• Click on the More Info button and wait for a response
• If Diagnostics returns data from the modem, then there is not necessarily a hardware problem try reinstalling the modem with the right drivers
  Note: If it returns no data, the machine should be looked at by a qualified computer hardware technician
