Too Limited! Program exits after displaying 15 codes or the first time you press the same key twice due to "'non-compatbility' between PC keybords." Limited to scan codes of standard keys only, no Ctrl, alt, key combinations.

Help: Serial Mouse   Posted by: Khurram on Saturday, April 23, 2005

Dear Dr. Bob,
I'm working on Serial Port(Seriall Mouse functionality). Since last 3 Weeks I didn't find the solution of my Question. Although I've tried many tricks but i didn't succeed yet.
You can write me an Algorithm.

Question:
I've serial Mouse with my System.
I want to check Status of Mouse Cursor (WITHOUT USING INTERRUPTS).
I mean i want to read data from Serial Port(Com1,Com2).
I'm working in Assembly Language, Although any Comp Language Program will be accepted.
How this task can be achived?

Answer of " Serial Mouse Status" would be Highly appreciated.


Sincerely,


Khurram Nazir.



Islamabad,
Pakistan.

While this is almost 20 year old code, it is well done. It displays knowledge of the O.S. operations, and still works in WinXP! Funny thing, some of the kids learning from this source code weren't born when it was written :-}

I wrote this code in 1989 to test custom programmed keyboards. I am surprise this thing is still floating around. I don't have the external modules to link in anymore. But it is easy enough to write them for use in my "call" statements. Enjoy.

Not all keys are scan codes some set flags   Posted by: Julie Altswager on Thursday, October 11, 2007

The piece of information I will inform you of is that not all keys on the keyboard send scan codes. The "Ctrl" and Shift actually set flags. Therefore it is reasonable for a scan code program not to display those keys. You can add that function and upload the updated code when you have it ready. Thanks, Julie.

This is a great Demo piece of code! It's not a full blown application, but I can take this snippet and use it in a bigger program. Thanks Dude!
