Sorry, I missed that detail. I just opened the connection w/ tip, went to the
window where I was setuid to uucp and did "stty olcuc </dev/cua/0" then back to
the tip window. No effect. Everything is still lower case.
At this point, I think I need to make a non-setuid copy of tip and run tip
under truss from a shell which is setuid to uucp. I'll have to wait until
tomorrow to try that though as other things will take up the rest of the day.
I'm beginning to suspect that there's something in the USB serial driver which
is being more "helpful" than it should. So another thing is to spin up OI on a
box w/ a real serial port and see how it behaves.
