Perhaps it's a bit of assuming spacecraft packet operations run like the
1990's terrestrial PBBS network.  Those did generally require a "hard
connect" and served a single user at a time.

There is no real traffic on the ISS PBBS.  All of the action is the UI
digipeater on 145.825 MHz.  There are a few parameter settings for your TNC
that differ from terrestrial operation.  I tried to summarize this at:
http://home.comcast.net/~k9jkm/ARISS_Packet_How_To/

Right now my page contains only the external TNC-2 configuration.  I'd be
happy to add links to pages explaining 'UI digi' via the ISS for the D700
radios and soundcards if ya'll could mention those.

The log at http://www.ariss.net/ shows 100's of stations enjoying UI
operation but those few attempts at a hard connection can be a showstopper
for the rest of a pass.
