[Bug 1094278] Re: cu doesn't connect properly to a serial console

[Michal Suchanek]

There are two issues here:

cu randomly identifies the serial connection as dialin (nortscts) ot
dialout (rtscts). I don't care about that distinction being broken. I
fix that with the patch.

The other problem is 'line in use' which is caused by running cu as
root. The permission issues are discussed above. You need to add
yourself to whatever group cu is owned by and run as non-root user
and/or change the permissions to make the device nodes owned by whatever
is cu suid to.
