Win32_SerialPortConfiguration - 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.

Description

The Win32_SerialPortConfiguration WMI class represents the settings for data transmission on a Windows serial port. This includes configurations for establishing a connection and error checking.

Example(s)

use strict;
use Win32::OLE('in');

use constant wbemFlagReturnImmediately => 0x10;
use constant wbemFlagForwardOnly => 0x20;
