Within a Serial Command
To enter control characters within a serial command, hold down the con-
trol key while typing the desired character.
Example:
<K141,CNTL-m> to enter ^M
Within an Embedded Menu
Control characters entered on the command line are displayed in the
menu as mnemonic characters, such as: <CR><NUL><NUL><NUL>.
To enter a control character from within an embedded menu, first type in
a space (with the space key). This has the effect of allowing the control
key to be recognized as a part of the control character. Next hold down
the control key while typing the desired character.
Example:
Space CNTL-m to enter ^M.
