Hi again,
I'm continuing my porting effort and
have gotten some good results, DHCP is working (which may or may not indicate
that UDP is working as well?) and I'm now trying to get a simple telnet
responder running on port 23. I've set up a socket waiting for a connection
ready to reply but when I try to telnet to the platform the initial [SYN]
gets the reply [RST, ACK] instead of [SYN, ACK]. from debugging it seem
to me that the tcp_input()-function can't find any active PCB.
my question is what is a PCB in this
context and where are they created? Are they created with the socket or
somewhere else?
Best regards
