[lwip-users] When TCP connection fails

[JM]

Easy question I hope:

(1.3.0, in Raw mode)

When I call tcp_connect() it immediately returns error-free as expected.  The question is, what happens when the connection fails, as in, the host never responds?  I thought maybe it calls the "connected" callback specified in tcp_connect() with an error after TCP_SYNMAXRTX retries, but this doesn't appear to happen.
