It should be doable but let me look back at the source. I haven't touched that code in a while and it may take me a few days because work is really crazy at the moment. I will reply here when I get an answer.

Yes, the ::connect is definitely doing something (it's called also for UDP), but as far as I know this should only set the default destination address:port.
In fact I'm able to send, and my equipment receives, packets using the standard tty_write... But I totally fail to receive. I was expecting / hoping to see a "bind" or "recvfrom" in your code ... no luck. So for me the mystery is how you are able to receive from the mount. But your code is nice and clear and I can't find the answer.
I still have a few things to try, eventually will manage to have this working, I hope.
Thanks for your time!

In my tests, using the code "as is", I can get data sent to destination, but nothing received.
Enlightenment, pleaseeee?
(I must say I'm a bit surprised of finding gemini specific code in the indicom files - I can understand sometimes there's no other way, though)
Thanks
I am the one who added UDP support. It is used in the Gemini telescope driver.
The UDP support was not designed to be a server or to do broadcast messages, just as an alternate way to connect other than TCP.

I think it may have to do with the Western GoTo Limit. Like Jasem said the software causes a meridian flip by issuing a goto with the same coordinates. What I think is happening is that if the mount has not crossed (or gotten close to) the Western GoTo Limit then the mount won't flip. I do not have a complete understanding of exactly how this setting works but if you haven't you should join the Gemini Yahoo group. There are many Gemini experts on that group that could explain the settings much better than I can.

if (fabs(targetPosition - initialFocuserAbsPosition) > maxTravelIN->value())
So it checks against current position vs initial position at all times to make sure it is within range.
There is documentation in INDI site, but here is a more up-to-date one: stellarmate.com/support/ekos/focus.html
