-{ ZLPortIO driver interface unit v1.20 }
-{ -----------------------------------------------------------------------------}
-{ Description: }
-{ This unit allow your application direct access port input and output under }
-{ all versions of Microsoft Windows® }
-{ Depends: }
-{ zlportio.sys ddkint.pas }
-{ You must distribute zlportio.sys with your application }
-{ Procedures and functions: }
-{ procedure zlioportread( const Port,DataType:dword ):dword; }
-{ procedure zlioportwrite( const Port,DataType,Data:dword ); }
-{ }
-{ function portreadb( const Port:dword ):byte; }
-{ function portreadw( const Port:dword ):word; }
-{ function portreadl( const Port:dword ):dword; }
-{ }
-{ procedure portwriteb( const Port:Dword;const Data:byte ); }
-{ procedure portwritew( const Port:dword;const Data:word ); }
-{ procedure portwritel( const Port,Data:dword ); }
-{ }
-{ Examples: }
-{ // get data bits from LPT port }
-{ databits := portreadb( $378 ) }
-{ // set data bits from LPT port }
-{ portwriteb( $378, databits ) }
-{ // The second parameter determine the databus length for operation }
-{ -----------------------------------------------------------------------------}
-{ Revision History: }
-{ 1.00: + First public release }
-{ 1.10: + Added new functions (portreadX,portwriteX) for convenience of usage }
-{ 1.20: + Added new function (zliosetiopm) for enabling direct access to ports}
-{ 1.30: + added compiler directives for correct compilation }
-{ 1.40: + added opportunity to run multiply instances client to driver }
-{ 1.50: - fixed bug with work under win98 }
