OK, I must change every i/o access of my application to a localhost:xxxx service, implement the same service at the same port in WinXP and in linux (service with i/o permission), run the service and then run my applicaton. it's right? oiaohm wrote: > > The kind of operation you are asking for is not simple to be made work. http://tldp.org/HOWTO/IO-Port-Programming-2.html#ss2.2 Note the warning there about using device port system can be completely exploited by any program giving that ablity. This also applies to Windows raw IO support.
