Could someone show us how to reconfig Consensys (Unix/386 SVR4) in
order to support more pseudo terminals?

Currently we have 16 pseudo terminals configured by default, but
we would want to increase the number to say 32.  We had tried
changing entries in /etc/conf/sdevice.d/pts, /etc/conf/sdevice.d/ptm,
and /etc/conf/sdevice.d/ptem then we ran /etc/conf/bin/idmknod to
create the device files in /dev. And we finally ran /etc/conf/bin/idbuild
to rebuild the Unix kernel.  The pts device files were created,
but we still cannot open more than 16 pseudo terminals.

I don't have Consensys, (I run microport 4.1,) but the following
should work:

I believe the values you need to change are the third column of
the /etc/conf/sdevice.d/ptm and /etc/conf/sdevice.d/pts files.
You would also need to change the /etc/conf/node.d/pts file
to tell idmknod of the new major/minor pairs. Follow the
convention of existing entries in the file. You then rebuild
the kernel using /etc/conf/bin/idbuild. You should shutdown
and reboot (I believe idmknod is called upon re-enterring
init state 2.)

I've actually never tried the above myself, since during the
installation I configured my kernel with 256 entrypoints. If
all fails, reinstalling the proper package (nsu for microport)
interactively might do the job.

Good luck,

-Ade.
