uPnP `MS Windows only, at this time`

This API allows you to discover UPnP compliant Internet Gateway Devices (Routers/Boxes) on the network and dynamically manage their ports.

Requirements:

Windows XP or above.
UPnP compliant Internet Gateway Device.
TCP port 2869 or UDP port 1900 being opened on Firewall if any.

Note: All functions are synchronous and wait response from the device. During that time, the application is frozen.
_UPNP_Connect is the worst freezing function (3-5 seconds), the others work much faster if the device responds immediately (which is not always the case).

_UPNP_Connect

_UPNP_OpenPort
fun [S S I I I] I

_UPNP_ClosePort
