Hello !
I've been asked how to do something I'm at a loss as to where to start - if
it's possible at all. To quote the person asking me:
Is there a way 1. to check the state of a port, 2. determine the application
using it?
By #1, I believe he means "determine if a comm port was in use".
Any ideas whatsoever would be appreciated. I believe #1 can be done by an
attempt to open the port as a file in "DENY_ALL" mode - if it fails, someone is
using it. I don't believe #2 is possible. If I could be corrected, that would
be great. :-)
