The replies I got all told me that I had to do the boot -r in order to have the
kernel reconfigured for the extra devices. Typical :-((
It was also pointed out that at SunOS 4.x the maximum number of Pseudo terminal
devices was configured in the kernel so the /dev/MAKEDEV script was only half the story.
This I accept but would like to say that the default kernel for a server allowed
a maximun of 256 Pseudo terminal devices and yet only 50 or so device files are made
by default giving plenty of headroom for using MAKEDEV to create extra devices.
For anyone else needing to change the pseudo terminal parameters the ones I have used are:
set pt_cnt=256
set npty=256
Thanks to all who replied.
