I have acquired an RCA VP-3501 Pamphlet/data sheet that lists the Escape codes.

I've tested them out and found out the RCA has 8 foreground and background colours. Two Colour modes (8 colour or 8 intensity), and two resolutions (40x24 or 20x12) with 128 definable characters displaying 6x8 pixels.

Doing the math...
40 * 6 = 240
24 * 8 = 192

So 240x192 or 120x96 pixels

The codes are as follows:

Mode: | CTRL Code | ESC Code
-----------------------|-----------|---------------------
Display OFF | | ESC ESC D 0
Display ON | | ESC ESC D 1
Resolution HI (40x24) | | ESC ESC R 1
Resolution LO (20x12) | | ESC ESC R 0
Reverse Video ON | CTRL O | ESC ESC S 1
Reverse Video OFF | CRTL N | ESC ESC S 0
Define Command Delim. | | ESC ESC X c

-----------------------|-----------|------------------
Bell | CTRL G |
Keyboard Tone OFF | | ESC ESC T 0
" " ON | | ESC ESC T 1

c = character
d = Decimal 0-9
h = Hex 0-F

I don't know why it says 16h's for a "pattern". I would have thought it would be 8...
