Hallo!

Actually I have never managed to drive a 3000/300 com port with more
than 9600 baud, neither under DEC Unix nor under NetBSD.  I have not
tried modems, but serial VT100 hardware which should support 19200 -
but it never worked with those 3000/300, only if I reverted to 9600.
(The same VT100 works flawlessly with 19200 baud on a PC with FreeBSD).
If you say it is not the chipset, maybe it is a problem in SRM or
something.

Of course if anybody has a solution, it would be great.
