The ESC (escape) character followed by the @ character turns inverse video on or
off and can be embedded in the message string. Example: “abcESC@defESC@
ghi” specifies the string “abcdefghi” where the “def” portion is displayed in
inverse video.
Example: “abcESC#defESC)ESC@ghi” specifies the string “abcdefghi” where
the “def” portion appears in the channel 3 color (magenta) and the “ghi” portion
appears in the normal text color except it’s in inverse video.
An alternate way to enter characters is octal escape sequences. This consists of a
backslash followed by numerals in the standard C language printf fashion.
