Hello,
The best answer seems to be to use fuser /dev/pts/* which gives a list of
processes using each pts device. These then can be looked up in a ps -efl
listing.
Similar to this is to use lsof (available from
ftp://vic.cc.purdue.edu/pub/tools/unix/lsof ) which I guess gives the
same information (I haven't got and build lsof yet).
ps -efl gives a partial list of pts's used, but it's not as complete as the
above method.
listing all the pts files using ls -l /devices/pseudo | grep pt gives a list
of all pt devices and who was lat using them. It does not show which are
currently used and which are free.

For anyone who needs to increase the number of ptys, I refer them to the
Soalris 2 FAQ for this list, but essentially it says put the following in
/etc/system and boot -r:
* System V pseudo terminals 80 of them
set pt_cnt = 80
For BSD style pttys there is another line:
set npty = 80
The FAQ says you probably don't need to do this as you should never run out
of BSD style ptys.
Tom.
