this is the output from the linux terminal

tcp_output_segment: 6509:6509
tcp_slowtmr: polling application
tcp_output: nothing to send ((nil))
tcp_slowtmr: processing active pcb
tcp_slowtmr: max SYN retries reached
tcp_pcb_purge
tcp_pcb_purge: data left on ->unacked


The callback function never was invoked, I put a printf() at the very
beginning, the message never been print out.

Thanks

Shan
