Ronald Thomas asked
There's something about writing a source file that is converted to a
terminfo entry by a 'tic' command. The source file is somewhat in the
style of the printcap entry for various printers, but much more complex.
You should be able to take the printcap entry and run it through
tic and have a valid terminfo file. Whether the terminfo file created
actually drives the HP I can't say as I don't run GRASS on my current
system.
Hope this helps - let me know if this works.
