Son of FAS?

[Richard Foulk]

I recall hearing that Equinox (or someone like that) equips their
smart serial card with a driver that doesn't use interrupts.  They
do some kind of polling from within one of the kernels inner loops.

Doing away with the interrupt overhead supposedly results in a marked
performance gain.  (Seems reasonable.)

My question is: couldn't this same technique be used to good advantage
with the fifo-ized dumb serial cards?

Since most smart cards gain mostly from the reduced interrupt load they
place on the system wouldn't this blur the difference a bit more?
