2.8 Serial Ports (COM1, COM3, COM4)
Figure 2.7:Serial Ports (COM1, COM3, COM4)
The PCE-7210 offers three serial ports COM1, COM3 and COM4. These
ports can connect to serial devices, such as a mouse or to a communica-
tions network.
The IRQ and address ranges for all ports are fixed. However, if you want
to disable the port or change these parameters later, you can do this in the
system BIOS setup.
Different devices implement the RS-232 standard in different ways. If
you are having problems with a serial device, be sure to check the pin
assignments for the connector.
