I got no response on a previous posting hope I second post will be luckier. -------------------- I just need to make sure that I understand the code correctly in the TCP stack. (We are trying to see how long the system waits before a SYN gets retransmitted.) When a SYN is sent, a keepalive timer is set with using the TCPTV_KEEPALIVEINTVL = 75hz (??ms - escapes me at the moment). So an ack must be received in this time frame??? This is not the usual dynamic tetransmission timer which might make sense for SYN packts. It seems like a retransmission timer should be set?? That's why I'm posing the question.
