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 d isplayed 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.
Another way to enter characters is \xnn where the nn is the hexadecimal value of
the character to display.
An advantage of these methods is that any controller program can be used.
Another advantage is it’s easy to access characters with the h igh bit set, that is,
t
hose characters with a decimal value greater than 127.
An alternate way to enter certain characters is with a backslash followed by a
single char acter (following “standard” Unix) as described in the table below.
n
Newline (carriage return and line feed)
\ Backslash (\\ is required to get a backslash character)
t
Horizontal tab; the next 2 characters specify the pixel column to tab to
as explained earlier
If a backslash is followed by an undefined special chara cter, the backslash is
ignored and the character following it is accepted as is.
NOTE. The use of any escape codes other than those described above may
produce unpredictable results.
