I'm beginning to feel like crazy , because I remember some sort of ZIPs containing source code in VC++ about receiving & parsing the UDP packets sent
by LFS through the insim port.

Any clue?

Thanks in advance.

We used to have one on the LFS site (source code for the LFSControl utility) but it has been deleted because it's a bit out of date, designed for S1.

In fact it should still work in almost all cases, so i've uploaded it for you... maybe it will help.

Thanks Scawen!
