There are not necessarily any "ACK frames" - if data is flowing both ways,
ACKs can be sent as part of a normal TCP data frame (actually: each TCP
packet contains an ACK number - so an "ACK frame" is a special case of
a TCP packet with no data content).
Also, modern TCP implementations don't send a single ACK per data packet,
but usually only an ACK for a number of received packets.
Can you show a dump of a few packets flowing back and forth?
