[ale] setting non-standard baud rate on serial port

[Steven A. DuChene]

I have an automotive diagnostic device that seems to only want to communicate
across the serial port at a baud rate of 8192 which is a non-standard baud rate.
When I try to use setserial or stty to set this baud rate on the port both
programs tell me "Invalid Argument"

stty -F /dev/ttyS0 8192
stty: invalid argument `8192'
Try `stty --help' for more information.

Anyone have any idea how to set baud rate on a serial port to a non-standard baud rate like this?
