If you use hardware flow control, be sure that these control signals are cor-

rectly wired or there may be loss of data.

TIMEOUT

Specify the number of seconds for session timeout. The CPS monitors data

traffic between your session and the attached serial device. If no data is

received or transmitted to your TELNET session, then your session will time

out after the number of seconds specified in this parameter.

SOCKET

In addition, the socket number for the serial port may also be defined. By

default, this value is 3000 plus the port number. This is the socket number

that should be specified on the TELNET client to connect to this serial port.

Upon successful completion of this command, the value is changed in the CPS

configuration database. The new socket number becomes effective after the

next reboot.

CLI

The CLI keyword can be used to enable/disable the serial CLI interface on a

CPS port. By manufacturing default, Port 1 has CLI=ASCII, but you may assign

the serial CLI to any CPS port. The value of the keyword indicates the type of

terminal connected to the serial port. This value can be set only on a single

port. If this value is set on port n, and is already active on port p, then the

CLI parameter is automatically set to CLI=OFF on port p. Upon successful

completion of this command, the value is changed in the CPS configuration

database. The new CLI setting becomes effective after the next reboot.

Accessing the Port History Buffer

For each CPS serial port, there is a history buffer that contains the last 64K

characters of data received from the attached serial device. This history buffer

is provided so that you may access data received from the attached serial

device even if there was no active session at the time the data was received.

This information may be invaluable in analyzing a possible server failure.

To view the serial port’s history, you must enter your CLI Access Character to

obtain a prompt from the CLI. For information on the CLI Access Character

see Changing the CLI Access Character in Chapter 4.
