CPort80 Class Reference
#include <Port80.h>
Detailed Description
Emulated port 80.Port 80 is a port without a real function, that is used to slow things down. Since our emulator is slow enough already ;-) this port has no function at all, but it needs to be there to avoid error messages about non-existing hardware.
