In OpenBSD, I use stty to change it (logged in as root) and it always bounces back to 9600.  Is there something else conflicting with the port speed?

As soon as the device is closed, it reverts to the default. So you have to set it from a process that keeps it open, or engage in some other trickery:


( stty 38400; myprog ) < /dev/ttyb 2>&1 > /dev/ttyb
