Well, the dz driver I have doesn't know that; its baudrate table just
lists 16 speeds from 50 to 19200.  And selecting the last of them does
indeed produce something close to 19200, or it wouldn't've worked when
connected to the other machine.

Hm, not sure whether I have _any_ turbochannel cards, nor for that
matter whether I have any FDDI interfaces for any of my other machines.

Fortunately, neither is needed at the moment.
