Hi Tito, the correct command would be var streamDebug=1
Do I understand it right that you get the values for 8 channels with one read? You would need to include these responses and sort them into different records by specifying the record names in the protocol.

Thanks for the replies. @ Mark Rivers: This FLNK field is just a relict from my very first attempts. This FLNK should keep the record going even though there is a mismatch. Using the SCAN field it is pretty unnecessary I admit, but it shouldn't be responsible for my problem - however I deleted the line now.
@ Fabian S.: I tried to enter "streamDebug=1" at the epics console but I got the message "Command streamDebug=1 not found". I don't really thinkg the output really appears in the input. When I take a look at the packages sent via telnet it looks like the out commands from the read_volt record are sent in between the out and in command from the set_volt record.
@ Dirk Zimoch: I'm using asyn4-21. As I see it my problem is that the device is not locked by a protocole once the first out command is sent (or may I just don't understand locking correctly) and that the response to the out command of read_volt is not unique for a specific channel (like it for example would be when the level and channel number would be part of the output - then I could parse these values.
I can't change the strings coming from the box unfortunatelly. So is there a away to actually check how and if a protocol really locks a device? Or is there the possibility to somehow manually lock the box - with a field for example.
I'm also thinking of using the DISA und DISV field. My basic idea would be to stop the read_volt record via first writing to the DISA/DISV field in the read_volt record so it no longer processes, then set the voltage and restart the read_volt record afterwards. I guess it may possible somehow.
