Serial Port

1.2.5 Serial Port
The serial port is fully programmable and supports asynchronous
communications. The 25-pin, D-shell connector provides the signals to
drive a device with a standard 25-contact RS-232 connector. The connected
device is identified by the system configuration as SERIAL 1 through
SERIAL 8. Adapters with serial ports also can be configured from SERIAL 1
to SERIAL 8. Conflicts occur with multiple communication lines if two or
more lines have the same address. Select the Set configuration option
from the system programs on the hard disk drive. Select View
Configuration to verify that no lines are addressed the same.
