Win32_SerialPort - WMI sample in Perl

The foundations for Manageability in Windows 7/2008/Vista/XP/2000 and Millennium Edition/'98 are Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself.

On this site, you can find many WMI samples.


Win32_SerialPort

Description

The Win32_SerialPort WMI class represents a serial port on a Windows system.

use Win32::OLE('in');
