All,
According to the Channel Access protocol specification from the Cosylab website, parameter 1 of the header of a CA_PROTO_READ_NOTIFY response contains the channel SID (the same as the request header received).
Is this correct? Monitoring network traffic from a 3.14.12 win32-x86 soft IOC, this value always appears to a fixed value of 1, no matter what the serverID, or clientID of the channel. Returning anything other than 1 also appears to break
correct functioning of a caget.
Thanks,
Graham
