Re: [lwip-users] what wrong with my tcp?

[乔崇]

dear Sir:
       At the afternoon,I link the lwip net with my pc with a point to piont 
net wire,my tcp works very well.
Then I pull out one end of the net wire.The tcp stopped.Although I plug it 
again,the tcp still stop there.
I the turn on IP_DEBUG on,the printed out messages show that when lwip send out 
a packet,the other end not receive
it,lwip stops there for ever.
       Maybe it need a tcp poll,but i do not know how to poll.I use 
netconn_write api.
       Help me!Thank you!
