Im working in a project using COM to comunicate to some hardware and i´m have a 
big problem: when I send some data to the hardware, it receives and send the 
answer in 50 microseconds or less, but, when my program receives the answer, 
theres 1 ms of delay until i can send a byte back to hardware. Its not my 
program fault, its some kind of windows or whatever issue because i make a test 
program that receive, send, receive, send one line below another to see it, and 
the delay is outside my program. Have it anything to do with some configuration 
tip or maybe a overlapped style can fix it?
someone?
