System: NetBSD phxtst08 1.3.3 NetBSD 1.3.3 (GENERIC) #0: Sat Dec 12 15:08:02 EST 1998 root@vlad:/usr/src/sys/arch/pmax/compile/GENERIC pmax


>Description:
The baud rate of /dev/ttyD0 and /dev/ttyD1 cannot be changed from 4800.
Methods tried were ioctls (termio), getty and stty.
Another clue is that at one point during the experiments there was a kernel
error message about an "LK201 keyboard" error.

It appears that the GENERIC kernel contains hard-coded assumptions that
the mouse and keyboard ports are, in fact, being used as such, even though
/dev/console is a VT320 connected to /dev/ttyD3.
	
>How-To-Repeat:
Connect a terminal to the mouse or keyboard port, set the corresponding
getty entries in /dev/ttys to "on", send a HUP signal to init, and note
the baud rate that works.
	
>Fix:
Change baud rate of connected terminal.  This is not an option for the
desired application.
