Hi Dario, I suggest you use socket stream and more specifically the ZdcSocketStream class. Socket is too low level, and web socket is for communications over HTTP. Noury

Ciao,
i have to manage bidirectional communications with a printing device.
For now from Pharo i open a TCP-IP connection on the device that acts as a server.
So from the program ( client ) i manage the synchronous transmission and reception
of the various commands to the device and everything is ok.
At this point it remains for me to manage - intercept on the client (Pharo)
the asynchronous transmission of commands by the server ( for example: the end of paper notification from the device )
How can i handle this?
At which level do you advise me to work? ( socket - socketStream - websocket - ....... ..... )
Any advice on this?
Thank,
Dario
