Sorry for this blunder!  I forgot to edit the Subject line before posting.

Here is my last article.
Baskaran.
I am using a MicroSoft Mouse (Bus version, not an InPort mouse), to collect
reaction time data in an experiment.  I am using hardware interrupt to detect
a button press which runs an ISR to get the time from a MetraByte Counter/Timer
card.  The problem is, the interrupt rate for the mouse is so slow that I have
only a 30ms resolution.  Is there a way of increasing the interrupt rate for
this mouse?  

You can do this for a MSoft InPort mouse by using a command line switch /R4
while loading mouse.sys; this sets the interrupt rate to 200Hz (once every
5ms).

I would appreciate any suggestions from the netters.

Thanks,

Baskaran.
