Folks,

	I asked a while ago if expect worked for HPUX.  The answer
was, "no", but it does now.  Many people sent me mail about it, and I
lost some of it, so here's the scoop:

	I talked to Don Libes (the author of expect) about it, and we
worked out the System V incompatibilities.  You can now get a copy
of expect from durer.cme.nist.gov via anonymous ftp, or get it by mail
using their server.  I don't know how the mail thing works.

	'expect' has a C library, but one command does not work on
HPUX, and I suspect it's the fault of HPUX, and not 'expect' because it
works on other systems.  I'd like some HP people to try to get the 
expect library routine 'exp_fexpect' to work.

	Until HP or NIST fix that bug, we programmers need to use
the command 'exp_expect' instead of 'exp_fexpect'.  Read the expect
man page for details.

	There is one last HPUXism, which is that getdtablesize is not
implemented.  Add this to the appropriate source file:
----------------------------------------------
#include <unistd.h>

int getdtablesize()
{
  return (sysconf(_SC_OPEN_MAX));
}
-----------------------------------------------
Thanks to Ian Hogg at Control Data Corp. for the above routine.
He tells me that he has some other such routines.

	Expect works well for me.  Don is receptive to bug reports,
so please report them.  expect is not extremely complicated, so any
remaining BSD SYSV incompatibilities should be fixable, and I'd like
the fixed if they exist.  So would Don Libes.  He admits that he has not
previously had any demand for expect to work on SYSV machines.
That means that people are not speaking up, not that there is no demand,
because I got quite a mail response about my posting from people who
wanted it to work.
