Overview

Product Information

Serial Connectors

You can attach a variety of pointing devices (such as a mouse or

trackball) or peripheral devices (including printers, plotters, modems,

and scanners) to the two Serial Input/Output (SIO) RS-232 ports on the

rear panel of this workstation. Consult the documentation that

accompanies each pointing device or peripheral device for speciﬁc

information concerning its use.

The SIO ports are programmable, allowing functions such as bit rate,

character length, parity, and stop bits to be set. You can set these by

using the HP-UX System Administration Manager (SAM) utility, or by

selecting a system special device ﬁle with the functions already

programmed. The SIO ports are used as an interface for serial

asynchronous devices to the CPU.

Table 1-2 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.
