7 Solving Problems

4Try resetting your modem by turning it off and on. If you are using DOS or Windows 3.1 communications software, make sure the ini- tialization string includes &F as the first command, to cancel any “leftover’ command that could affect the modem’s operation.

If you don’t get an OK, the problem may still be in the communica- tions software. Make sure you have done whatever is necessary in your software to make a port connection. Not all communications programs connect to the COM port automatically. Some connect when the software loads and remain connected until the program terminates. Others can disconnect without exiting the program. The modem’s TR indicator lights to show that the software has taken

4control of the modem through the COM port.

Your communications software settings may not match the physical port the modem is connected to. The serial cable might be plugged into the wrong connector—check your computer documentation to make sure. Or you might have selected a COM port in your software other than the one the modem is physically connected to—compare

4the settings in your software to the physical connection.

If the modem is on, the cable is plugged into the correct port, the communications software is configured correctly, and you still don’t get an OK, the fault might be in the serial cable. Make sure it is firmly connected at both ends.

Is this the first time you have used the cable? If so, it may not be wired correctly. Check the cable description on the packaging to

4make sure the cable is the right one for your computer.

Peripheral expansion cards, such as sound and game cards, might include a serial port preconfigured as COM1 or COM2. The extra seri- al port, or the card itself, may use the same COM port, memory address, or interrupt request (IRQ) as your communications port. Be sure to disable any unused ports.
