Yes, StreamDevice can receive messages sent by the device automatically. The record must use SCAN „I/O Intr“ and the protocol starts with an in command instead of out.

For a more specific answer I need more details on your device. Does it use TCP or UDP? How to configure where it sends to? This is needed to use the correct type of asyn port.



Hi Dirk, 

    I have a feature question about stream.

    I have a device, communicated with PC throuth network card. The process was done by itself, I mean it send and recevie automaticly without EPICS.

    And could I got the receive message,using EPICS stream? 

    I puzzled that, normally stream send the out command, then get the in message. Now the device send and recive by itself, could stream( in PC) get the in message?

Regards,

Liang
