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.
# ls -l /dev/cuaa
crw-rw---- 1 uucp dialer 12, 128 Feb 21 18:52 /dev/cuaa
# ls -l /dev/ttya
crw-rw---- 1 uucp dialer 12, 0 Feb 24 22:31 /dev/ttya
They match what they should be but it still comes up device not configured.
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
