Special Keys Used in Console Program Mode
Explanation of use
Thrminates the command line so the console program can execute
the command.
This is used to delete single characters within a command line.
On video terminals and video monitors, the character(s) deleted
disappears (the console program sends a BS/SP/BS). On hardcopy
terminals, the deleted characters are retyped after a backslash
delimiter as they are deleted. For unknown attached console
devices, the console program assumes they are hardcopy.
Aborts the current command. The current \JIOgram mode PC will
be
displayed, and the console prompt >>> is displayed on the next
line. The console program echoes this
as
"C.
Causes the console program to throw away transmissions to the
console device until the next

is entered.
lctrll@]
is echoed
as
"0 when it disables output, but is not echoed when it reenables
output. Output is reenabled if the console program prints an error
message or if the console prompts for a command from the console
device.
Output is also enabled
by
entering program J/O mode, and by
lctrrl

Retypes the current command line. Deleted characters are not

The console program supports
lctrll

and

normal and attached console devices. These keys are equivalent to
the corresponding line pacing control characters XOFF and XON.
Characters received between the XOFF/XON pair may
be
ignored.
The hold screen key on the normal console device is not used for
line pacing.
