Serial Port Connectors

Serial ports are used to communicate with printers,

plotters, external modems, auxiliary terminals, and other

computers. The server provides two serial ports (1 and 2).

You can add more serial ports by installing a serial adapter

in one of the expansion slots.

Serial ports transfer data

asynchronously

; they can

transmit any number of bits at any time, with no restriction

on the duration of the pauses between characters.

The serial ports transmit and receive data and commands

at a rate of 300 bits per second (bps) up to 115 200 bps.

The bits-per-second measurement is commonly referred to

as the

baud rate.

Both of the serial connectors on the server use a 9-pin,

D-shell connector.

Table 9 shows the pin-number assignments for the serial

port connectors. The pin-number assignments conform to

the industry standard.
