You need to use READ-IO when you a) want the raw data and b) don't
want to wait for the remote part to close the port. COPY/PART had
a similar functionality on /BINARY TCP ports, but it still waited
if there were no data in the port. Now you can just use COPY or
COPY/PART, because it no more waits for data.
Imagine a client-server communication. With the new experimental
core:
Asynchronous communication:
Server:
>> listen: open tcp://:10000
>> conn: first listen
Client:
>> conn: open tcp://localhost:10000
>> insert conn "hello server!"
Server:
>> copy conn
== "hello server!"
>> insert conn "hello client!"
Client:
>> copy conn
== "hello client!"
and so on.
Synchronous communication:
Server:
>> listen: open/wait tcp://:10000
>> conn: first listen
Client:
>> conn: open tcp://localhost:10000
>> insert conn "1234567890"
Server:
>> copy/part conn 20
(waits...)
Client:
>> insert conn "1234567890"
Server:
(ends waiting)
== "12345678901234567890"
You don't even need to use a cycle if you use syncronous
operations (which you can use if you don't need to handle
multiple connections or other events).

Gabriele.
