I've noticed this as well, or at least I assume my symptoms are the
same. I set up a getty line with a Hayes 9600 Ultra on a 386BSD system
with a FreeBSD kernel (yeah, yeah, I know; I'll upgrade the rest later)
and the SIO+BIDIR drivers. Dialing in at 9600 was fine, but I have a
SupraModem 2400 at home. When connecting at 2400, it would work for a
bit, but when the system tried to send a burst of data quickly, it
would start out fine and come out garbled after a few lines. I replaced
the Hayes with a US Robotics Courier 2400, and the problem went away,
but I would like to be able to dial out at 9600 on the dialin line
using the BIDIR feature. Is there a workaround for this, or will it
require a fix?
