Not a kernel issue. Your ttyC10 - ttyC15 are not "legal" tty names in
Linux. It would really be nice if Cyclades and Comtrol would get a grip
and realize these names cause major headaches to nearly everyone when
they're first exposed to them. Limit yourself to 2 characters after tty,
and the problem goes away. The same goes for cub/cuc/cur/etc.

Here's a little script that will make you 64 utmply correct ttyC devices
and the corresponding cuc's.


@port = ('0'..'9','a'..'z','A'..'Z','_','^');

foreach $i (@port) {
system("rm -f /dev/ttyC$i /dev/cuc$i /dev/cub$i");
system("mknod /dev/ttyC$i c $major_t $minor");
system("mknod /dev/cuc$i c $major_c $minor");
system("chown root.tty /dev/ttyC$i /dev/cuc$i");
system("chmod 666 /dev/ttyC$i /dev/cuc$i");
print "made $i\n";

note1: The minor number here is for the older 1.2 and 1.3 kernels before
it was moved to 0.
note2: The perms I set may not be good for you...but my system is a
terminal server, where nobody but me gets they're not too
important to me.
