NAME
IO::Tty - Low-level allocate a pseudo-Tty, import constants.
VERSION
1.16
SYNOPSIS
use IO::Tty qw(TIOCNOTTY);
...
# use only to import constants, see IO::Pty to create ptys.
DESCRIPTION
"IO::Tty" is used internally by "IO::Pty" to create a pseudo-tty. You
wouldn't want to use it directly except to import constants, use
"IO::Pty". For a list of importable constants, see IO::Tty::Constant.
Windows is now supported, but ONLY under the Cygwin environment, see
<http://sources.redhat.com/cygwin/>.
Please note that pty creation is very system-dependend. From my
experience, any modern POSIX system should be fine. Find below a list of
systems that "IO::Tty" should work on. A more detailed table (which is
slowly getting out-of-date) is available from the project pages document
manager at SourceForge <http://sourceforge.net/projects/expectperl/>.
If you have problems on your system and your system is listed in the
"verified" list, you probably have some non-standard setup, e.g. you
compiled your Linux-kernel yourself and disabled ptys (bummer!). Please
ask your friendly sysadmin for help.
If your system is not listed, unpack the latest version of "IO::Tty", do
a 'perl Makefile.PL; make; make test; uname -a' and send me
(RGiersig@cpan.org) the results and I'll see what I can deduce from
that. There are chances that it will work right out-of-the-box...
If it's working on your system, please send me a short note with details
(version number, distribution, etc. 'uname -a' and 'perl -V' is a good
start; also, the output from "perl Makefile.PL" contains a lot of
interesting info, so please include that as well) so I can get an
overview. Thanks!
VERIFIED SYSTEMS, KNOWN ISSUES
This is a list of systems that "IO::Tty" seems to work on ('make test'
passes) with comments about "features":
* AIX 4.3
Returns EIO instead of EOF when the slave is closed. Benign.
* AIX 5.x
* FreeBSD 4.4
EOF on the slave tty is not reported back to the master.
* OpenBSD 2.8
The ioctl TIOCSCTTY sometimes fails. This is also known in
Tcl/Expect, see http://expect.nist.gov/FAQ.html
EOF on the slave tty is not reported back to the master.
* Darwin 7.9.0
* HPUX 10.20 & 11.00
EOF on the slave tty is not reported back to the master.
* IRIX 6.5
* Linux 2.2.x & 2.4.x
Returns EIO instead of EOF when the slave is closed. Benign.
* OSF 4.0
EOF on the slave tty is not reported back to the master.
* Solaris 8, 2.7, 2.6
Has the "feature" of returning EOF just once?!
EOF on the slave tty is not reported back to the master.
* Windows NT/2k/XP (under Cygwin)
When you send (print) a too long line (>160 chars) to a non-raw pty,
the call just hangs forever and even alarm() cannot get you out.
Don't complain to me...
EOF on the slave tty is not reported back to the master.
* z/OS
The following systems have not been verified yet for this version, but a
previous version worked on them:
* SCO Unix
* NetBSD
probably the same as the other *BSDs...
If you have additions to these lists, please mail them to
<RGiersig@cpan.org>.

AUTHORS
Originally by Graham Barr <gbarr@pobox.com>, based on the Ptty module by
Nick Ing-Simmons <nik@tiuk.ti.com>.
Now maintained and heavily rewritten by Roland Giersig

Contains copyrighted stuff from openssh v3.0p1, authored by Tatu Ylonen

<Todd.Miller@courtesan.com>. I also got a lot of inspiration from the
pty code in Xemacs.
