Linux driver for
        Red-Eye Serial: A serial remote control interface for
                        Pace(r) Digital Cable Receivers

=== === === === === === === === === === === === === === === === === === ===

White Wing Logic make a serial-controlled IR transmitter for controlling
Pace(r) digital cable receivers as used by some CableTV companies in the
UK (notably Telewest).

The original software for Linux was written by Malcolm Smith and was
distributed from the website with no copyright, license or attribution.

I decided to rework the code to compile under GCC 4.x and a 2.6 kernel.
in the process I added some debug control to the original, and a little
argv handling, though very fragile.

I have offered this code to White Wing Logic and also to the MythTV 
project in the hope that others find it useful.

Installation

Compile the source
        $ gcc -o red_eye red_eye.c

Copy to bin directory and set permissions
        $ cp ./red_eye /usr/bin/red_eye
        $ chown root:root /usr/bin/red_eye
        $ chmod 0555 /usr/bin/red_eye

Test the binary
        $ red_eye

        usage: red_eye deviceComPort sendString waitSecs [debug]
         -or-  red_eye sendString [debug]
        
         where deviceComPort   is e.g. /dev/ttyS0
               sendString      is your desired command to the RedEye Serial
               waitSecs        is pause time after command (in seconds 0-9)
               debug           is debug level (0=off, 9=max)

        $ red_eye 101 2
