i have a game running in win xp SP2.
this game used in Internet Caffe (like casino game).
there is owner soft and client (client=game), each one is installed in diferent computer and all are wired thrugh special controller attached to each RS232.
i will explain a how it work :
This game work and get inputs from other computer with owner soft
Both owner soft and game don't start if the controller is not attached to com1 in each computer .
each computer have his own controller and they wire together with telephone cable.
the admin soft can control 20 games (computers with game and controller).
the dealer can do many action in the clients from the admin computer, such as send or remove credit, see game meters or enter into game setup.
i was able to trace with serial port monitor the strings that come from the admin soft to clients computer such as "credit in" or "credit out" .....
the problem is that every time there is different strings for each operation (the protocol is encrypted?). my goal is to identify the files that manage this protocol and change it so the game will work with other controller (i have my own controller).
i have electronic engineer working with me so there is no problem to make changes to my controller hardware and soft.
i can give you access to any computer you need - game or admin soft.
