I thought one of its schemes was right for SCO, given the right
parameters, but I see I was mistaken. Someone would need to write an
OpenPTY function for the SCO scheme -- no big deal. Ah, yes, I see that
the version on Skunkware 5 (screen 3.5.1) is configured with the BSD
style function, but only checks ptys ttyp0 through ttyp9 -- you'd run
out of screens immediately. The version I was messing with recently
(3.7.1) still doesn't have a SCO pty function.
