•If the modem reports BUSY, the other number may be busy, in which case you should try again later, or it may indicate that you have failed to add a 9, prefix to the phone number if you must dial 9 for an outside line.
If you must dial 9 to get an outside line, the easiest way to dial it automatically using legacy software is to include it in the modem’s dial prefix, e.g., ATDT9,.

You might have dialed a wrong number, and a person answered instead of a computer, or you might have dialed the correct number but the other computer or software was turned off or faulty. Check the number and try again, or try calling another system to make sure your modem is working. Also, try calling the number on your telephone. If you hear harsh sounds, then another modem is answering the call, and the modems may be having problems negotiating because of modem incompatibilities or line noise. Try connecting at a lower speed by setting register S37 to a lower rate (e.g., by typing ATS37=11 in the terminal window and pressing ENTER) and then calling again.
