If a nonroot user starts tcsh in complains about permissions for /dev/port. Although this seems not to affect the further session, it is somehow a bug. If logging in as root user or su'ed in somewhere this problem does not show up. I hope you know a way to get rid of this ugly messages.

I could not replicate this problem on a standard 6.0 install machine with kernel-2.2.5-22 installed.
