Maybe someone can explain this...
I noticed that when a socket (regular or datagram) is opened to Windows
(via my app that is listening on port 1901), an 'alias' port is given
instead of the 'real' one. For example, if my external device (computer,
PDA, etc.) connects to socket 192.168.77.10:1901 for communications, the
actual socket reported is a random number (like 1407), and it changes each
time the device connects (incrementally..1408, 1409, 1410).
Is this Windows or RunRev?
John,
If I understand correcly what you've written, that's the normal TCP/IP behaviour. When a client connect to a server via a give port, the server will accept the connection and move the connection to a whole random free socket so that it can keep accepting connections on the given port (in your case, 1901). That's the standard way...
that way, you can connect two or more clients to the same server...

PS: hum... I think a little network foundations primer would be good... shall we write one?
Thanks, JR
