[Expectperl-discuss] problem with opening non-default pty on Solaris

[<kw...@nw...>]

All,

I'm new to this group.  May be the problem I encounter is
a simple and well known one.  Any help is appreciated.

Solaris is configured with 48 pairs of pseudo-terminal by
default (/dev/ptyp0 to /dev/ptyrf).  But on some of the
machines I work with, they have been configured to provide
over 120 pseudo-terminals, and the first 70 or so pairs are
claimed by some daemon processes.

When my perl-expect script is run, it fails because it (or
IO:Pty) attempts to open the first 48 pairs and finds that
none of them are openable - in other words, it does not
realize that there are more non-default pty's available
in the system.

*  My question is, therefore: Is there a tunable parameter *

*  the other non-default pty's?                            *

Help is appreciated very much.

Ideally, Expect or Pty should automatically look up some
config file (or even just look into /dev to see how many
pty?? terminals have been set up) to figure that out by
itself.
