- I'm reasonably sure that an H19 is an H19, and isn't compatible with
- anything. Back in the days when a terminal cost as much as a whole
- system does these days, in the early 80's, it was almost a standard
- among hobbyists and so forth, and then Televideo brought out some
- cheaper terminals. These days, you can't get people to pay shipping to
- take these things off of your hands. check your local BSD system, you
- may find a termcap for an H19. One of the early releases of PC/IP's
- telnet client would only do H19 emulation. Hmmm....as it turns out, I
- have compiled terminfo entries for the h19, but not source.

- You would set the environment variable 'TERM' to whatever you wanted
- the terminal to be.
