Hi James,
In my experience what works well is to create an input record for each valid response format. Use SCAN="I/O Intr" on these input records; streamDevice will automatically look for matches in parallel.
Separately, create an output record (SCAN="Passive") to send out the command.
It may be possible to create a regular _expression_ that matches all your valid formats. Creating multiple input records turned out to be simpler in my case.
Thanks, -Chris Ford SLAC

I’m using streamDevice to handle serial data with a protocol file.
I can get two different valid responses to the same command. Below are the protocol strings that match the two different responses:
%(\$1:C)f;L1;%(\$1:L1)f;;%(\$1:F1)f %(\$1:C)f;;%(\$1:F1)f
What’s the easiest/most sensible way of making it accept either response?
I got it working by making one of the strings a mismatch condition but this means the record‘s severity is raised.
Thanks for any advice,
James
