Ohhh, I see what I did. It was a network byte-ordering problem. I wanted
it to connect to port 2022 (07e6 hex), but it was switching the bytes around
such that I was actually connecting to port 58887 (e607 hex). My eye had
been skipping right past the captured packets because I assumed they were
for some other protocol!
Thanks for you the help, Guy and Anne.
(I am relatively new to using email lists such as this- will Anne also get
this message, or do I have to reply specifically to her email in order for
her to see it?)

I send data from the client computer to the server computer using a
regular TCP connection onto port 2022 of the server. I know the server
is receiving the information, because it is able to print it on the
screen.
Wireshark seems to be capturing other data just fine, such as HTTP
traffic on port 80, and VNC traffic (I use that to fiddle with my server
so I don't have to walk back and forth between my computers).
Is it capturing other traffic *between the client and server in question*?
