Re: Direct I/O
Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance
If it's a 16-bit app, you could use an NTVDM VDD. Another option is to use
some kind of exception handler (perhaps via a program acting as a debugger)
to trap STATUS_PRIVILEGED_INSTRUCTION, examine the opcode, and perform the
correct action. If you have source though, I would think that fixing the
app is far easier.

Hello !
I've an old software (for win95 & 98) who accessing the serial port com
for
communicate with automatism... But this software is accessing directly to
the
port com (with IN & OUT C) . With win95 & 98 it's ok, but with nt2000 and
xp
not.
How can i write a driver for intercept I/O from my application and write
to
serial port com ?
Thank you
.
