You may then use one of the following commands :

PORT HISTORY

Rights Required: None

A 64K history buffer is maintained for each CPS port. Each buffer is a

circular queue that contains the last 64K of data that has been received from

the attached serial device. The buffer begins filling with received data upon

completion of CPS initialization, even if no user is connected to the port. When

you connect to a serial port, data received from the attached serial device prior

to the connection is available in the buffer. Data received from the attached

serial device during the connection is also added to the port’s history buffer.

Upon termination of the current TELNET session, the port history buffer is

cleared and all data in the buffer is discarded. In addition, the history buffer may

be manually cleared using the PORT HISTORY CLEAR command.

Data contained within the port history buffer may be viewed at any time

using the PORT HISTORY command line interface (CLI). Upon entering PORT

HISTORY command mode, the CPS will display the text TOP OF BUFFER

followed by the first 23 history display lines.

The PORT HISTORY CLI mode will be indicated by a unique CLI prompt:

PORT HISTORY >

The following commands are supported by the PORT HISTORY CLI mode.

Only the first letter of a command needs to be entered.

BOTTOM The history view location will be set to the BOTTOM of the

file minus 23 history display lines, if available.

CLEAR Clears the port history buffer.

NEXT Increments the current history display line by the number of

lines per page and a new history display page is output.

PREV Decrements the current history display line by the number of

lines per page and a new history display page is output.

QUIT Returns to the normal CLI.
