42 MCG-3 Color Micro Character Generator
R R R R RL R L R L R L R L REA EA EA EA EAD LI D LI D LI D LI D LIN N N N NE E E E E
PURPOSE: Reads one line from the MCG-3 memory.
FORMAT: R R R R RL,p,l L,p,l L,p,l L,p,l L,p,l
p = Page number 1 through 10
1 = line number 1 through 9
DESCRIPTION: This command reads any line in the MCG-3 memory,
given the page and line number. Results are in ASCII. However, if a
character is displayed in bold (meaning BG-Background is On) or is
flashing, the corresponding ASNI.SYS codes will also be sent.
Codes are defined as follows:
Function ANSI code
Bold on ESC[7m
Flash on ESC[5m
All attr. off ESC[0m
Note that ESC is ASCII code 27d.
EXAMPLE: If the string THIS IS A TEST is in the MCG-3 memory at
page 1, line 1 and the word IS is flashing the sequence read by the
command R R R R RL, L, L, L, L,1 1 1 1 1,,,,,1 1 1 1 1 would be:
THIS ESC[5misESC[0m A TEST
followed by a carriage return (13d), and line feed (10d).
If there were no flashing or bolded characters the sequence read would
be
THIS IS A TEST
again followed by a carriage return (13d), and line feed (10d).
