  13. <H3>SUMMARY</H3></FONT><FONT FACE="Verdana" SIZE=2><P>
  14. The sources in this directory build the parallel.sys driver that ships in Microsoft&#174; Windows&#174; 2000. ParClass is the bus driver for the "parallel bus." ParClass is responsible for creating the \DosDevices\LPTx device objects that user-mode applications use to access (read, write, and so on) the "raw" parallel port. ParClass is also responsible, as the bus driver, for detecting all parallel enumerable devices connected to the port and creating a PDO for each such device.<P>
  16. ParClass is a kernel-mode driver that runs on all platforms supported by Windows 2000. The driver compiles using both the 64-bit compiler and the x86 version of Microsoft Visual C&#174; 6.0; however, test coverage of the driver under 64-bit and x86 Visual C 6.0 is unknown. The driver supports Plug and Play and Power Management, but Power Management support is minimal.<P>
