RS-232C Serial Input/Output Connectors

You can attach peripheral devices to the RS-232C Serial Input/Output
(SIO) ports on this computer. Peripheral devices include printers,
plotters, modems, and scanners. Consult the documentation that
accompanies each pointing or peripheral device for specific information
concerning its use.
The SIO ports are programmable; that is, you can choose attributes such
as bit rate, character length, parity, and stop bits either by selecting the
corresponding device file (in /dev), or by using SAM (the System
Administration Manager). The SIO ports are used as an interface for
serial asynchronous devices to the CPU. The ports operate at up to a
115.2Kbaud rate.
The table below shows the SIO connector pin listings. The serial
connectors are 9-pin D-sub connectors. Signal names are those specified
in the EIA RS-232 standard.

SCSI Connectors

Use the Narrow Single-Ended SCSI connector and/or the Wide LVD
(Low-Voltage Differential) SCSI connectors to connect external SCSI
devices such as hard disk drives, optical disk drives, DDS-format tape
