Asif,

No I haven't and it is because VFP is the wrong tool for that job. That job screams for VC++ or some other low level language. VFP is a high level database management language and it is not architected to handled hardware interrupts well under program control.

I can equally ask you if you have ever drilled 128 holes for lag bolts into 12" deep concrete with a hand held drill.
