Hi there,
we have Aloha Spy setup in TCP with a Video surveillance unit. We are able to see data flow but it's clearly not the whole receipt stream.

At a network level this is what it looks like:

My guess is this is predicated from RS-232 protocol where it's expecting an acknowldgement response before it sends more data. Can someone please help?
