K10 is not a valid TERMCAP feild name. KA is key 10. If you find a K10 in
the entry you'ld do well to get it changed, as it will break many a program,
not mine, but many others.

Terminal graphics are really outside the scope of Termcap. Terminfo can
probably handle them, but Termcap was never designed to deal with anything
but BL through TILDE.

If people find your programs useful they will be able to set up their own
TERMCAP file to deal with them: "setenv TERMCAP $HOME/termcap". It is probably
inadvisable to require graphics character sets in a termcap program, as many
terminals don't support them... certainly damn few terminal emulators do.
Or you could go with curses/terminfo... speaking of which: does anybody nearby
baylor or hyd-ptd have the PD curses/terminfo source lying around?
