209 If Something Goes Wrong Resolving a hardware conflict Modem problems This section lists common modem problems. The modem will not receive or transmit properly. Make sure the RJ11 cable (the one that goes from the modem to the telephone line) is firmly connected to the computer's modem port and the telephone line socket. Check the port settings to make sure the hardware and software are referring to the same COM port (look in Device Manager under Modems for the built-in modem). Check the communications parameters (baud rate, parity, data length and stop bits) specified in the communications program. It should be set up to transmit at 300, 1200, 2400, 4800, 9600, 14400, 28800, 33600 bps (bits per second) or higher. Refer to the program's documentation and the modem manual for information on how to change these settings. The modem is on, set up properly and still will not transmit or receive data. Make sure the line has a dial tone. Connect a telephone handset to the line to check this. The other system may be busy or off line. Try making a test transmission to someone else.
