Hi Simon,
I also need to do the same (it is in my todo list).
The reaso to do so is quite reasonable: I am connecting to a server over
GPRS, I have a list of servers and I try all of them sequentialy twice.
The probelm is that each SYN is billed and thus excesses have to be avoided.

I am using lwip 1.3.0. I want to check this before reporting to
bugtracker... maybe it is already fixed.
If I set I timeout for the socket, and then read even if there is no
data available, it returns 0 but I can never send anything anymore using
that socket:
millis=10;

This was well tested, in fact it took me a full day to find the problem

Hi Simon I remember and I understand what you are doing.
What I am trying to find is someone else that could keep track of actual
bugfixes (preferably with yout help) and release a set of minimal
changes to 1.3.2.
It could be called 1.3.2a, b, c...
Any volunteers?
