replacing the cable.
n Check the device setting in the Windows Control Panel,
[Start > Settings > Control Panel > System > Device
Manager], and in the BIOS to be sure that the port is
enabled. If the port is disabled, the system won’t communi-
cate with any external devices connected to the port.
n Make sure the port is set properly to the correct value
(COM1 or COM2) to activate the serial port. Check the
device settings in the Windows Control Panel and in the
BIOS. If it is set to another value and you have made no
change to avoid the conflict with another device, set it to the
correct COM port. (COM 1 usually is the default one.)
