+{ 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 }
