Reply to Midifighter -> RS232 protocol

Hi guys!

I'm using a discontinued product which utilises RS232 standard to control some software on Windows XP.

It's a simple Matrix (8 buttons horisontal and 7 buttons vertical like when you call a bomb in the battleship game - A 8 - etc.)

The production is as mentioned discontinued and it is getting harder to obtain used boards and therefore i'm wondering if it is possible to use a Midi Fighter to gain the same result.

What i am interested in is to use the midifighter product in some kind of extended version eventually in the full matrix so you dont have to call A before 8 but there is a direct A8 button.

The Midifighter should, to avoid too much flashing and so on, just send midi signals to a piece of software which emulates the RS232.

I have one of the mentioned boards in stock - it would be possible to "rip" the RS232 commands to port them to the software.
The original software reads the RS232 from a COM port defined in the configuration - That could probably be assigned to a virtual com port without problems.

The software is freeware and it is possible to test it without any other hardware than a Midifighter (or maybe the emulator it self).

As i havent read any copyright notices, licenses and so on i have not mentioned any hardware ID or manufacturers. If you have guessed what product i'm talking about please don't mention the Name as i don't want to get in to any problems

Is there anybody out there that can help me.
If the issue is solved there will be a reward if the software is complex to make.
