<H3>SUMMARY</H3></FONT><FONT FACE="Verdana" SIZE=2><P>
|
|
Serenum enumerates Plug-n-Play RS-232 devices that are compliant with the current revision of Plug and Play External COM Device. The specification is available at <a href=http://www.microsoft.com/hwdev/download/respec/pnpcom.rtf>http://www.microsoft.com/hwdev/download/respec/pnpcom.rtf</a>.<P>

|
|
It loads as an upper filter driver to many different RS-232 device drivers that are compliant with its requirements and performs this service for them. <P>

<H3>BUILDING THE SAMPLE</H3></FONT><FONT FACE="Verdana" SIZE=2><P>
|
|
To build the sample, run the <B>build</B> command. Once built, the sample produces one binary: Serenum.sys. The sample is 64-bit compliant, works on both x86 and Alpha platforms, and supports both Plug and Play and Power Management. There is no one Inf for serenum because it is loaded as a filter driver in different driver stacks. An example of this can be found in %WINDIR%\inf\msports.inf. <P>
