Communication between Symbolics & Sun using TCP

My essential problem is this: I can establish a connection with the Sun and it
will attempt to send me a message. I, however, don't know when the message
arrives because my server function (defined through neti:define-server) is
never invoked. Shouldn't this functionality activate when a message is sent
to the port specified through tcp:add-tcp-port-for-protocol ? Note that i did
not say that i don't receive the message sent. If i peek at the contents of
the buffered input stream, the message is there, but it never gets pushed on
my message stack!
The server function is invoked when another machine initiates a connection
to the Lispm. If the connection is initiated by the Lispm, then it's the
client, not the server. You should be reading from the stream that was
opened by INIT-TCP and processing that input.
You might be better off making use of the RPC facilities rather than using
TCP directly. In addition to handling the interaction better, it also
takes care of the byte ordering for you.
