<background>,<size and shadow>,<timeout>,<message bytes>” (variable bytes)
Clears current text, displays text message over video (normal) or blank
background. The built-in character generator can accept up to 40 characters of text
(including carriage returns), 28 characters per line. Use a hex $0D or decimal 13 in
the text as a carriage return, which will advance CG to the next line, first space on
the right.
Start Line - 1-11
Text Color - 1-7= White
Text Background Color – 0-7=Transparent (no background)
Full screen background – 0=normal insert over video, 1=blank screen (blue)
Size and Shadow – 0-3=small text with drop shadow
Time-Out – 0=15-second display, 1=persistent
Persistent text stays on screen until the next DM command a new Menu or channel
is selected.
Ex1:
“$A5,<dh>,<dl>,10,‘DM’, 2,7,0,0,1,0,’TEST’ ” displays the word TEST on the
second line, white text, inserted over video, small size with drop shadow, and
timing out after 15 seconds.
Ex2:
“$A5,<dh>,<dl>,2,‘DM’ ” clears on-screen display, also clears persistent text
