NetBSD 1.0A (PLUTO) #2: Mon Jul 24 09:14:55 EDT 1995     ken@pluto:/usr/obj/i386/sys/arch/i386/compile/PLUTO

>Description:
	Only the first serial port can be used as console port, and only
	at 9600 baud.
>How-To-Repeat:
	add "options COMCONSOLE=0" to your config file, hook up terminal
	to second serial port at 19200 baud, gee it doesn't work.
>Fix:
	

two diffs, against com.c 1.61 and comreg.h 1.6

see comment changes in comreg.h for config info.
