Hi Jez, /etc/ttys lists a ton of pseudo terminals, which is great. However, after opening up 32 pseudo terminals (/dev/ptyp[0-9] and /dev/ptyp[a-v]]), none of the other terminals are used (eg. /dev/ptyq*). How do I get the system to start using those devices? (The /etc/ttys entries for /dev/ttyp* are identical to the /dev/ttyq* entries.) Justin
