I made this some years ago in DOS making a program for smart cards.
The most important experience - one should not make delais in input or
output data flow for testing purposes because the device (in my case smart
card) breaks the operation due to time out.
In WinNT, Win2000, WinXP You cannot access the port directly how in DOS. You
should write a driver but I never made this in Windows. Please seek "writing
driver" somewhere in Internet. I seen this also on Microsoft page.
