[Suns-at-Home] IPX Serial port speed (OpenBSD)

Yes.  They can go substantially faster (614400, I think) if you don't
mind a comparatively high probability of input errors.  This is OK in
some circumstances (eg, if your use case is output only), though,
because of the input error thing, a lot of OSes' drivers won't do that
out of the box.

Almost certainly, what's happening here is that when stty exits and
closes the line, nothing has it open and thus it resets to the OS's
default settings, including speed.

Admittedly, I don't know OpenBSD specifically.  But all the Unix tty
line experience I have has worked that way.
