- This is a 94-byte set that can be designated to any of G0..G3.
- The final character of the designation sequence is ">":
-
- ESC ( > designates the DEC Technical set to G0
- ESC ) > designates the DEC Technical set to G1
- ESC * > designates the DEC Technical set to G2
- ESC + > designates the DEC Technical set to G3
-
- NOTE: this character set and final character of the designation sequence
- are NOT registered with the ISO.
-
- The values listed below are for GR, i.e. they are 8-bit values. Subtract
- 128 for use in GL.
-
- The graphics listed here in the control region (128-159) are from the HDS
- 3200 terminal manual. The DEC VT340 manual shows that DEC does not use the
- control area for graphics: "Characters and symbols often used in technical
- applications, such as schematic and logic diagrams. The C0 controls are in
- columns 0 and 1. The graphic characters and symbols are in columns 2
- through 7. You can use the characters in positions 2/1 through 3/7 to form
- large composite characters. You can use the DEC Technical Set to replace
- the ASCII set in GL or the DEC Supplemental Graphic set in GR. You can only
- use the DEC Technical Set in VT300 mode."
-
- The DEC manual does not name or describe the characters in any way. The
- names below are best guesses.
