Sockets

[Brian Yennie]

This is off the top of my head, but hopefully it helps. It basically 
just expects 1 line of input over the socket, and then echos it back.
Note that you don't have to use the "with message" syntax, but if you 
don't then your program will block when doing reads and writes from the 
socket, which is bad if you need to handle multiple connections.

on startServer portNum
    accept connections on port portNum with message "newConnect"
end startServer

on stopServer portNum
   close socket (portNum)
on stopServer

on newConnect s
   read from s for 1 line with message "firstLine"
end newConnect

on firstLine s,data
   write "GOT IT::"&data to socket s with message "doneWriting"
end firstLine

on doneWriting s
   close socket s
end doneWriting

on socketTimeout s
   ## a read or write timed out on this socket
end socketTimeout

on socketError s
   ## some other socket-related error
end socketError
