Useful Control-Key Sequences
exists, the monitor displays an error message (F?). Otherwise, control remains
with the foreground job until redirected to the background job (with
CTRL/B
), or
redirected to a system job (with
CTRL/X
), or until the foreground job terminates.
In multiterminal systems,
CTRL/F
has no effect if the foreground console is not
shared.
CTRL/F
has no effect when used under a single-job monitor, or when a
SET TT NOFB command is in effect.
To Suppress Terminal Output (CTRL/O)
CTRL/O
suppresses terminal output while continuing program execution.
CTRL/O
echoes as ^O on the terminal. RT–11 reenables terminal output when one of the
following occurs:
• You type a second
CTRL/O
.
• You return control to the monitor by typing
CTRL/C
or by issuing the .EXIT
request in your program.
• The running program issues a .RCTRLO or .MTRCTO programmed request
(see the RT–11 System Macro Library Manual). RT–11 system programs reset
CTRL/O
to the echoing state each time you enter a new command string.
To Resume Terminal Display After Stopping It (CTRL/Q)
CTRL/Q
resumes displaying characters on the terminal from the point the display
previously stopped because of a
CTRL/S
.
CTRL/Q
echoes but has no effect under a
multiterminal monitor if a SET TT NOPAGE command is in effect.
To Suspend Terminal Output (CTRL/S)
CTRL/S
temporarily suspends output to the terminal until you type a
CTRL/Q
.
CTRL/S
does not echo. Under a multiterminal monitor,
CTRL/S
is not intercepted
by the monitor if SET TT NOPAGE is in effect.
To Cancel/Delete the Current Command Line (CTRL/U)
CTRL/U
cancels the current input line (all characters back to, but not including,
the most recent line feed,
CTRL/C
, or
CTRL/Z
).
When SL is running,
CTRL/U
erases the current input line from the screen and
from the command buffer. When SL is not running,
CTRL/U
echoes as ^U followed
by a return and line feed at the terminal.
To Direct Keyboard Input to a System Job (CTRL/X)
CTRL/X
causes RT–11 to prompt you for the name of a job to which it then directs
all further keyboard input.
When you type
CTRL/X
, RT–11 displays the Job? prompt at the terminal. In
response, specify the system-job name (or logical-job name) of the system job to
which you want to direct input. Specify B or F to direct keyboard input to the
background or foreground job, respectively.
If the specified job does not exist, RT–11 displays a question mark (?); otherwise,
RT–11 displays the system-job name at the terminal. Control remains with
the specified system job until the job terminates or control is redirected to the
