The devices can be called anything at all in /dev; the kernel refers to them as /dev/tty0n, which in Debian's context is incorrect, as we called them /dev/ttySn. It could be permission problems, but since you seem to be root that's unlikely. Check for locks on the device in /var/lock. hamish -- Hamish Moffatt, StudIEAust [EMAIL PROTECTED], [EMAIL PROTECTED] Student, computer science & computer systems engineering. 3rd year, RMIT. http://hamish.home.ml.org/ (PGP key here) CPOM: [****** ] 60% Your train has been cancelled due to defective government at Spring Street.. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
