Within a Serial Command
To enter control characters within a serial command, hold down the control
key while typing the desired character.
Example: <K141,1,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.
