I've tried all the suggestions so far but no luck.  I can not ever get 
/dev/cua* to work properly.

Even cat fails:

# cat < /dev/cuaa
ksh: cannot open /dev/cuaa: Device not configured


So the fundamental problem is this "Device not configured" error.  How 
is OpenBSD supposed to be configuring these devices and why is my system 
not doing so?  This is a completely clean install of OpenBSD on the 
machine after completely formatting and repartitioning the hard drive.

There's something missing and it's probably something simple but I've 
stared at it for so logn now that I'm likely missing it entirely.

according to sys/arch/sparc/sparc/conf.c, zs uses major device number 12.

Check the device majer/minors: /dev/ttya should be 12,0 and
/dev/cuau 12,128.

They match what they should be but it still comes up device not configured.

In that case I'm out of suggestions. I dont't have a machine to reproduce.

Well, looking at the code, it seems that sparc's sz(4) just does not
do cua and never did. I suspect the man page is wrong. Does /dev/ttya
work for you? Of course using it for both incoming and outgoing will
not fly...
