NO IT IS NOT.
COM3 and COM4 require interrupt sharing, and the default serial driver
will *NOT* do this.

*I* am certainly not regretting your decision! 8-)
the original serial driver was a piece of crap (it was based on
a serial driver for the HP300, which has a somewhat
different set of constraints placed on it...).
i'll be glad to see it go away.

AMEN.
bde's driver has some serious problems: configuring it is
totally broken, but i guess people are working on that...
if not, i know somebody who wants to...
also, it requires his NPX patches, which screw some people
with 386/387 combos...
