    EnumPorts - Find the system's COM and/or LPT ports

    The EnumPorts class will find the COM ports, LPT ports, or both. If a new device arrives or leaves the list of devices gets refreshed.

    The information you can retrieve is:

    • PortDescription
    • PortName
    • PortNumber
    • PortType


    These can be retrieved by index from 1 to Count or by key (PortName, e.g. "COM1:").

    Each refresh raises the Refresh event so you can update a menu, etc.

    Menu item clicked on, Form1 printed some of its info


    No special requirements, but Windows 2000 or newer is required. Only tested on Windows 10 1709.
