Port History Mode Commands

Command	Description
Bottom	B sets the view location to the bottom of the ﬁle minus 23 history
	display lines, if available.

Clear	C clears the port history buffer.

Next	N increments the current history display line by the number of lines
	per page and outputs a new history display page.

Prev	P decrements the current history display line by the number of lines
	per page and outputs a new history display page.

Quit	Q returns to the normal CLI.

Resume	R leaves port history mode and CLI mode and resumes the session
	with the attached serial device. This single command is equivalent to
	sequentially using the Quit and Resume commands.

Search	S searches the port history buffer for a speciﬁed text string. Search
	strings with embedded spaces must be enclosed in quotes.
	By default, the search is case sensitive. To ignore case, enter -ibefore
	the string. To specify direction, type -uto search up from the current
	line toward the top of the buffer or -dto search down from the current
	line toward the bottom of the buffer. The search direction remains in
	effect for subsequent searches until you change the search direction.
	If the string is found, the current history display line is set to the line
	containing the string, and the CCM outputs a history display page. If the
	string is not found, an error message is displayed, no other information
	is output and the current history display line is not changed.
	Entering the Search command with no parameters searches again
	for the previous string in the same direction as the previous search.

Top	T sets the current history display line to one and outputs a history
	display page.

The following examples assume the user is in port history mode.

The following command searches the history buffer in the upward direction for the string Abort Process.

PORT HISTORY> s -u “Abort Process”

The following command searches the history buffer for the string Process, ignoring case.

PORT HISTORY> s -i Process
