I guess I don't consider 128000 arbitrary... ;-) Seems like a major
shortcoming of the kernel to limit baud rates to such a small number of rates
when there are so many devices using other rates for very good reasons... like
we are with the CP210x.

This is what POSIX defines, sorry, can't do much about that.

Basically, in Mono I'm setting comport.BaudRate = 128000; but in looking at
the
log, it's getting set to 9600 so something strange going on there.

I would file a bug with Mono to get that looked at first.

If I understand correctly, the driver is part of and ships with the 2.6 kernel
(http://www.etheus.net/CP210x_Linux_Driver)... so when you say "it could be
added", what exactly are you saying? Added to the kernel or added to the
driver?

Added to the driver which is part of the kernel, which is where the driver
lives
that you are using here.
