Both cua01 and tty01 give the same result:
/dev/tty01: Device not configured
link down
I believe it is a cable problem but I have not had time to resolve it yet.

cua doesn't wait for handshaking, so it may work.

The response now is that the link is down. The cable only uses rxd,
txd and sg. The others are all tied together. The Sun has at least
one signal pulling the others high but the pc does not. I need to
add another wire to pull the handshake inputs high but won't have
time for that until late tonight.

And what is the response now?
You should be using cua01 not tty01.

I restored the dialer group to /dev/tty01 and added the user to the
dialer group as Nick suggested. It still doesn't work but the
response is different now. I believe there is a cable problem now.
The cable works with a Sun Ultra 10 but not with the PC running
openbsd.
Thank you for the help.

Hello,
A user needs to connect to external equipment using tip and a serial port.
I created an /etc/remote file:
snake:br=9600:dv=/dev/tty01:hf:nb:pa=none
The group associated with /dev/tty01 was changed from dialer to one that
includes the user:
$ls -l /dev/tty01
crw-rw---- 1 uucp wheel 8, 1 Feb 7 09:38 /dev/tty01
so, the user is already in wheel group. Revert above change. Enable
sudo (if not already done so) for users in group wheel.
$ sudo -u uucp tip snake
--patrick
uh...if all else fails, do it as root? I think we'd prefer to avoid
that, unless really a root-like activity.
The "dialer" group is set up just for this purpose.
The problem with changing the ownership (or group) of a device file is
the next upgrade will overwrite your ownership change. Ask me how I
know. Better idea, don't -- just use your imagination.
I'm not sure why you didn't just add that user to group "dialer", but it
is quite straight forward:
/home/nick $ grep nick /etc/group
wheel:*:0:root,nick
wsrc:*:9:nick
dialer:*:117:nick
nick:*:1000:
and...I (as "nick") have no trouble using my serial port without using
sudo and without changing device file ownership.
You will probably want to create a file /var/log/aculog which is
writable by group "dialer", as well... Squishes an error message, and
provides some useful logging, too.
Nick.
