Turbo PMAC On-line Command Specification 258
<CONTROL-H>
Function: Erase last character.
Scope: Port specific
Syntax: ASCII Value 8D; $08 (<BACKSPACE>).
This character, usually entered by typing the <BACKSPACE> key when talking to Turbo PMAC in
terminal mode, causes the most recently entered character in Turbo PMAC's command-line-receive buffer
for this port to be erased.

On-line command <CTRL-O> (Feed Hold All)
<CONTROL-I>
Function: Repeat last command line.
Scope: Port specific
Syntax: ASCII Value 9D; $09 (<TAB>).
This character, sometimes entered by typing the <TAB> key, causes the most recently sent alphanumeric
command line to Turbo PMAC on this port to be re-commanded. It provides a convenient way to quicken
a repetitive task, particularly when working interactively with Turbo PMAC in terminal mode. Other
control-character commands cannot be repeated with this command.
Note:
Most versions of the PMAC Executive Program trap a <CTRL-I> or <TAB> for
their own purposes, and do not send it on to Turbo PMAC, even when in terminal
mode.
Example:
This example shows how the tab key can be used to look for some event:
PC<CR>
P1:10<CR>
<TAB>
P1:10<CR>
<TAB>
P1:10<CR>
<TAB>
P1:11<CR>

On-line command <CONTROL-Y>.
<CONTROL-K>
Function: Kill all motors.
Scope: Global
Syntax: ASCII Value 11D; $0B
This command kills all motor outputs by opening the servo loop, commanding zero output, and taking the
amplifier enable signal (AENAn) false (polarity is determined by jumper E17x on Turbo PMAC boards)
for all motors on the card. If any motion programs are running, they will be aborted automatically.
(For the motor-specific K (kill) command, if the motor is in a coordinate system that is executing a motion
program, the program execution must be stopped with either an A (abort) or Q (quit) command before
Turbo PMAC will accept the K command.)
