For a port access under windows 2000 & XP you need a driver. There is a freeware driver : DriverLINX Port I/O Driver for Win95 and WinNT. It's an old one, but it's running without problems under windows 2000 and XP.

You can get the driver from : http://www.driverlinx.com/Software_Products/softwareproducts.htm

Here is a code for the Borland C++ Builder 4.0 to work with the driver above.

Code:

1. First you have to declarate the function pointer:
typedef void( __stdcall *pOutPort)(DWORD m_addr, DWORD m_value );  

2. Then load the dll:
HINSTANCE dllport = LoadLibrary( "dlportio.dll" );
if ( dllport == NULL )     
{Application->MessageBox( "dlportio.dll not found.","DLL - error", MB_OK );
return;     } 

3. Now initialize  the pointer :
pOutPort OutPort;  

4. Calculate the funtion address:
OutPort = ( void(__stdcall *)(DWORD m_addr, DWORD m_value))
GetProcAddress( dllport, "DlPortWritePortUchar" );

5. Call function:
OutPort( 0x340, 0x55 );

6. Free DLL: 
FreeLibrary( dllport );

Like this?

Code:

If OpenLibrary(0, "dlportio.dll")=0
  MessageBox("DLL - error", "dlportio.dll not found.", #MB_OK)
Else
  CallFunction(0, "DlPortWritePortUchar", $340, $55)
  CloseLibrary(0)
EndIf

It's not without problems on W2K and XP, i used it many years in my RAIDmonitor app on NT4 servers, and had to rewrite all to use another driver for W2K server.

You might want to look at http://www.beyondlogic.org/porttalk/porttalk.htm and try his device driver.
