This looks like a problem in the cy driver. AFAIK it should be
impossible to open cuaXX if ttyXX is open, but I don't see where in
the driver this is enforced.
It's not. cyopen looks a lot like comopen did before I fixed it. I suspect
both were derived from the same broken source at some time in the past.
It wouldn't be hard to copy the relevant parts from comopen to fix this, but
I don't have any Cyclades cards either so I can't do it.
