Terminal Input/Output Control

 

 

When entering a command at the prompt, the following control codes may be

 

 

entered for limited command line editing.

3

Note

The presence of the upward caret, “^”, before a character

 

indicates that the Control (CTRL) key must be held down

 

 

 

 

while striking the character key.

 

^X

(cancel line)

The cursor is backspaced to the beginning of

 

 

the line. If the terminal port is configured

 

 

with the hardcopy or TTY option (refer to the

 

 

PF command), then a carriage return and

 

 

line feed is issued along with another

 

 

prompt.

^H

(backspace)

The cursor is moved back one position. The

 

 

character at the new cursor position is erased.

 

 

If the hardcopy option is selected, a “/”

 

 

character is typed along with the deleted

 

 

character.

<DEL>

(delete or rubout)

Performs the same function as ^H.

^D

(redisplay)

The entire command line as entered so far is

 

 

redisplayed on the following line.

^A

(repeat)

Repeats the previous line. This happens only

 

 

at the command line. The last line entered is

 

 

redisplayed but not executed. The cursor is

 

 

positioned at the end of the line. You may

 

 

enter the line as is or you can add more

 

 

characters to it. You can edit the line by

 

 

backspacing and typing over old characters.

When observing output from any 197Bug command, the XON and XOFF characters which are in effect for the terminal port may be entered to control the output, if the XON/XOFF protocol is enabled (default). These characters are initialized to ^S and ^Q respectively by 197Bug but may be changed by the user using the PF command. In the initialized (default) mode, operation is as follows:

^S

(wait)

Console output is halted.

^Q

(resume)

Console output is resumed.
