transferred (i.e. the number of data bytes in the TCP packet, not the whole IP packet). The ack number is the next seq expected. Best way is to sniff a TCP session. For instance, if a password is entered, say to access a router, the password is transferred character by character and you will see the seq numbers increment by one. You need to pay attention to the direction of the flow.
If you need an example, post me directly and I'll look through my sniffer traace library. Cheers, Fred.
