Nice, thank you!
Even has its own bdf converter - I wrote mine a few years ago, just to
have more fonts to load into wsdisplay. Since gooeymux uses wsdisplay
fonts I may have to steal some fonts...
Hmm, looks like they spent a lot of code on pty handling ( I guess
forkpty() didn't exist back then ) and keymaps ( gooeymux doesn't have
any built in, it just reads them via ioctl(WSDISPLAYIO_GETMAP), that
way we can support any keyboard the kernel supports and inherit the
kernel's active keymap )
I should do the ioctl(TIOCCONS) thing as well so we get console output.
Also, looks like poll() didn't exist back then...
This would be difficult to get going on recent NetBSD since it attempts
to talk directly to ADB and graphics devices using interfaces that have
been replaces by wscons.

Yeah, I need to implement scrollback and copy/paste.

have fun
