Why does my application fail to connect/dial now that I am using NetModem?
The 2 most common reasons are a bad phone number or a modem driver issue. Phone Number issues: Verify that the telephone number is entered correctly (1+area code for long distance, any access codes you may need for an outside line such as 9 before the number.) You may also try plugging in a standard analog phone and try to dial the number to verify that the phone line supports outbound or long distance calls. Modem driver Issues: On the server side check that there is not more then one modem driver assigned to the COM port, byt going to Control Panel > Phone and Modem Options > Modems. If more then one modem driver is assigned to the same COM port, NetModem Server will not be able to open the port correctly. On the client side check the installed modem drivers to make sure they match the modem drivers installed on the server side. if these drivers are not an exact match it can cause connections to fail due to mismatched “AT” commands. Therefore it is always best to use the same version
