I am trying to write something using ATP.  I use the parameter block format
calls described in IM5.  When my computer is disconnected with the selfsend
flag on, I can send messages to myself without difficulty.  If I take two
computers and connect them together with both disconnected from the net, they
can communicate.  However, if I connect to the net, the GetResponse never
sees any of the messages - SendRequest does decrement retryCount (true with
one or two macs trying to communicate).  When I open the ATP socket, I use
0,0,0 for socket, node, net which SHOULD mean the socket can receive from
anywhere.  I noticed that when computers are disconnected from the net that
they also have a net # of 0 but when connected, different things listed by
NBP have different nets.  Am I doing something wrong network wise?  Do I have
to send things to a bridge to get bounced back, or what?
