IBM Personal System/2 CL57 SX User Manual

1.2.5 Serial Connector
The serial connector is fully programmable and is capable of asynchronous
communications at a maximum speed of 19.2 kb/s. The 9-pin D-shell
connector provides the signals to drive a standard EIA-232D device. The
connected device is identified by the system configuration as either
SERIAL_1 or SERIAL_2.
If an optional communication slot with a serial adapter is installed, the
device address must be different from the primary one.
Note:
Conflicts occur when two or more devices have the same address.
Use the
Set configuration
from the system utility programs stored
on the hard disk. Select
View configuration
to verify that no
ports have the same address.
