5.4 Console Command Language Control
Characters
Eleven ASCII control characters have special meaning when
you type them on the console terminal running in console
mode. See Table 5–3.
Table 5–3: Console Control Characters
Character Function
BREAK
Increments the console baud rate, if enabled.
CTRL/C
Causes the console to abort processing of a command.
CTRL/O
Causes the console to discard output to the console terminal un-
til the next
CTRL/O
is entered.
CTRL/P
In console mode, acts like
CTRL/C
. In program mode, causes the boot proces-
sor to halt and begin running the console program.
CTRL/Q
Resumes console output that was suspended with
CTRL/S
.
CTRL/R
Redisplays the current line.
CTRL/S
Suspends console output on the console terminal until
CTRL/Q
is typed.
CTRL/U
Discards all characters on the current line.
DELETE
Deletes the previously typed character.
ESC
Suppresses any special meaning associated with a given character.
RETURN
Carriage return; ends a command line.
BREAK
increments the console terminal baud rate to the next higher rate and
displays a new console prompt. If you use BREAK at the highest baud rate,
the program "wraps around" to the lowest rate. You can quickly synchronize
the console baud rate to the console terminal if the default speeds do not
match. To do this, hit BREAK repeatedly until the console prompt ">>> "
appears. The baud rates are 300, 600, 1200, 2400, 4800, 9600, 19200, and
38400. (Model 600 does not support 38400.) It is not recommended to run
faster than 1200 baud.
CTRL/C
aborts processing of a command. Echoed as ^C, CTRL/C also resumes
output which you suspended using CTRL/O. When you type CTRL/C as part
of a command line, the line is deleted as if you entered CTRL/U.
