You need to do two things after you decide how many terminal sessions
you need:

	1. Edit your kernel config file the default says:

		pseudo-device	pty	16
	=

	change it to any value up to 128 and generate a new kernel.

	2. run /dev/MAKEDEV as root to create the new devices, use these
	commands serially:

		./MAKEDEV pty1		(for total of 64)
		./MAKEDEV pty2		(for total of 96)
		./MAKEDEV pty3		(for total of 128)


Don't get carried away, these things take resources (as will more
simultaneous terminal sessions). To go from 16 to 32 just requires the
new kernel (apparently), but anything higher will require creation of
new devices too.
