Notes
Initializes the user character set to make wide vertical bar
graphs.
Initializes the user character set to make narrow vertical bar
graphs.
Initializes the user character set to make horizontal bar
graphs.
Draws a vertical bar graph at column [col] of length [length].
Length is measured in pixels (0x00 to 0x20). User must first
use the 'v' or 's' command to initialize characters.
Draws a horizontal bar graph starting at column [c] on row [r]
with direction [d] (0 is right, 1 is left) of length [length]. Length
is measured in pixels (0x00 to 0x64 if starting in column 1).
User must first use the 'h' command to initialize characters.
Defines one of 8 custom "user" characters. Character
number is [c] between 0x00 and 0x07. The 8 bytes are
described in section 4.1.6.
Notes
Turns off the underline cursor.
Turns on the blinking block cursor.
Turns off the blinking block cursor.
Moves the cursor one position to the left. If the
