Win32_SerialPort jscript sample code | ActiveXperts Network Monitor

The foundations for Manageability in Windows is 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. The Win32_SerialPort WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

Description

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