NAME ^

IO::Tty - Low-level allocate a pseudo-Tty, import constants.

VERSION ^

1.10

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 A more detailed table (which is slowly getting out-of-date) is available from the project pages document manager at SourceForge http://sourceforge.net/projects/expectperl/.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":

The following systems have not been verified yet for this version, but a previous version worked on them:

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 <RGiersig@cpan.org>.

Contains copyrighted stuff from openssh v3.0p1, authored by Tatu Ylonen <ylo@cs.hut.fi>, Markus Friedl and Todd C. Miller <Todd.Miller@courtesan.com>. I also got a lot of inspiry from the pty code in Xemacs.
