SubjectRe: 921Kbps on Linux: is it possible ?!?!

I've never even been able to get 460K to work correctly. I bought a
highspeed serial board

ttyS01 at 0x02f8 (irq = 3) is a ST16650V2

that had some sort of "multiplier" on it (so you could use it when your
OS/app didn't support the higher speeds). Setting it to 460x1 never
worked, 230x2 didn't, but 115,200 x 4 did.

I would get effects like that of irq conflicts (stuttered throughput, but
never higher than, oh, 10cps).

After moving enough jumpers to last a lifetime, I gave it up and stuck
with the 115 x 4 setting.

This was under 2.1.x>50<115 so it may be working now.
