Driver: QNX4
Author: Mike Gorchak
Status: Just a few words and patches.
Revision: $Revision: 1.4 $

I. What QNX4 driver supports:

1. Supports qnx/qnxm terminal protocols via termlib library.
2. Supports mouse on raw console and under pterm and qnxterm.
3. Supports almost all key combinations under raw console.
4. Supports pterm - Photon qnx terminal emulator. But it is very slow and
   without some key combinations support due to internal pterm problems.
5. Supports cpterm - Cyrillic Photon qnx terminal emulator by InfoMarket
   (http://www.infomarket.ru). It's resonably fast and stable. With mouse
   support.

II. Some notes before you starting using TurboVision under QNX4:

1. Before compiling TurboVision you must have the latest updates for the
   Watcom C/C++ 10.6, including patch A and patch B.
2. Watcom C/C++ 10.6 Patch A and B have broken unis3s.lib library which
   damages registers during function call, so you must download the fixed
   one from the http://mama.indstate.edu/users/liug/unix3s.lib .
3. After that (important!) you must install or reinstall the latest EGCS 1.1.2
   for the QNX4 from the http://www.jcmichot.usenet-fr.net/gcc/ .
4. You must obtain the latest perl version 5.x from the QUICS at the
   ftp://ftp.qnx.com/usr/free/ . Or better obtain latest perl 5.8.1 from
   the http://mama.indstate.edu/users/liug/perl-5.8.1-bin.tar.gz .
5. To successfully run TV under X11 and xterm drivers you can download
   latest XFree86 for QNX4 from the http://sf.net/projects/openqnx .


Attention! EGCS 1.1.2/QNX4 distributive have some errors in headers, so before
           compiling TurboVision you must apply the following patch:
