Hi again,
When I perform a tcp_write() to a remote server I find that the actual
<PSH, ACK> (observed using ethereal) does not occur until I receive some
data into the client application. For you information I am confident
that the tcp fast and slow timers are being called and when data is
received into the client application I observe a successful transmission
to the server and a consequent <ACK>. I have spent a fair few hours now
trying to track down what I believe to be a problem, but I am now
questioning my own sanity. Is it the case that in the lwip
implementation that the tcp_write does not get processed until data is
received or am I missing something else?
Regards Jimi
