I'm trying to figure out how to created and load a "soft character set"
into a vt220 terminal. These documents:
https://vt100.net/shuford/terminal/dec_vt220_codes.txt, and
https://vt100.net/docs/vt510-rm/DECDLD.html, seem to talk about how to do it, but I
don't follow this well. I'm guessing the fonts are made up of escape sequences.
Then I guess they are loaded by simply printing them to the terminal. If that's the
case, where are the examples of such sequences?
Playing around with vttest, there's an option to "Test Soft Character Sets"
in the "VT220 Tests" menu. But I get the error message "You did not
specify a font-file with the -f option". Where can I find examples of that file?
Putting these together, I'm guessing what vttest wants is a file containing sequences
described in those two documents. So, where do I go from here?
