TIOCREQCHECK error using Expect

[Rich Kennedy]

Hi,

The basic problem is getting the following
error while using Expect on a HP-UX platform.

ioctl error on TIOCREQCHECK: invalid argument

The issue was discussed without resolution
on dbForums, including comment from Don
Libes, author of Expect.

These scripts never have the issue on
Sun SPARC systems, and, until now, ran
well on HP-UX.

My suspicion is that some patch this year
has modified some aspect of the pty interface.

Since my target platform is HP-UX and
cannot be easily swapped for a different
platform, I am stuck running production
scripts on HP-UX. I can really use a
workaround for this problem.

There is a program trace on dbForum. I
hope an HP-UX engineer can take a look at it
and give some feedback.

Thanks
