Re: UDP problem

UDP could loose packets "by design" so there is no reason why sendto should
return an error.
If you need reliable connection use TCP or build some "packet loss"
detection in the UDP
protocol you are using.

Why this is happening in your case I have no clue, but you should not relay
on short cable or absence of collisions.
