Darrin> Hi all --

A small one. I sometimes have (I think) this problem. I never
checked the interrupts in /proc/interrupts, so I can't be sure of
that symptom. For me it has been an intermitent problem though, only
occuring when I warm-boot from dos (about once an ice-age). So I cold
boot and it works fine.
For me it is /dev/cua3 to my internal modem so I am _positive_ it is
your serial cable :). Well at least as much as it is mine. I haven't
noticed any missed characters, but it seems to have a serial
transmission rate of about 120s/char or it feels like it.
Oh, if it makes any difference to anyone I'm running kernel 2.0.0, and
my serial port is on irq 2 and I run it as a 16450 because somehow I
think that more accurately reflects reality.
I was messing so hard one day I even got an kernel oops because the
serial driver had unloaded and I was messing with set serial trying to
make it work. I'll have to dig up that oops one of these times and
