Yes, this should/will be better.  Here's how I personally deal with this now:

1. use 'tee /etc/addpty.cmds | devices' to create a script of commands to feed
   to devices.  There is some minor trickiness here, so I'm embedding a uuencode
   of my version of addpty.cmds:

begin 644 /etc/addpty.cmds
;82!P='ED978@<'1S(`H*;F\*"@H;6S`P,W$*
`
end

   Then use 'devices < /etc/addpty.cmds' up to the limits of your desires or
   the configured maximums.

   Note that this sort of strategy also works with other menu oriented commands,
   e.g., ndtable, that don't have a non-menu version.  If anyone wants my
   ndtable scripts, I'll be glad to mail/post them.

2. If you want to go above the default maximum of 16, in /etc/master up the
   ptybuffers value and the maxminor values for uptc and upts.  Rebuild the
   kernel (cd /usr/sys;make), put it in place and shutdown/reboot.  Then add
   additional stanzas to /etc/ddi/pty for the new pty's.  ("Yes, this should/
   will be better.")

man pages come by default with AIX/370.  With the RT, they are a separate
$50 PRPQ, with the number I and others have previously posted: P91026.
