Error 676 The phone line is busy.

The line is busy.

First check that the user is dialling the correct phone number. This error occurs if they are dialling their own number.

Check also that the modem is connected properly to the phone line. If the user has two sockets on the back of the modem then make sure that the line from the phone jack on the wall goes to the one marked LINE and not the one marked PHONE (that is for a handset)

Make sure that the POP the user is attempting to connect to is not busy. If it isn't then it is most likely a problem with the user's phone line. Make sure that the line they are tring to dial out on is not in use.

Sometimes this error occurs if the modem is a British Model and the user is not using the British to Irish adapter. Check if the modem is compatible with the Irish phone system by typing ati7 in Hyperterminal. If it says that the modem is British or another country then make sure that the user is using the correct converter.
