I've managed to use Netremote to communicate with Girder, which sends commands to my Onkyo PR-SC886 processor. I use the Onkyo gml/lua file in the download section. All the commands work great, and when I for instance send the master volume request, I get:

Serial: Onkyo-Ts-Sr-804 : Command queued: 21 31 4D 56 4C 51 53 54 4E !1MVLQSTN at postion 1
Serial: Onkyo-Ts-Sr-804 : Simple Send: 21 31 4D 56 4C 51 53 54 4E 0D !1MVLQSTN.
Serial: Onkyo-Ts-Sr-804 : Simple Receive: Data Code: 0
Serial: Onkyo-Ts-Sr-804 : Simple Receive: Data 21 31 4D 56 4C 33 31 1A !1MVL31. Code: 8192
Serial: Onkyo-Ts-Sr-804 : ERROR: Incomplete response to last command


The feedback (here "!1MVL31") is correct. I don't know why I get the last error message.

I just started learning this, and what I need your help on is to get this feedback message back into Netremote and display this in a slider/button. How do I get this value into a variable in Netremote.

I appreciate any help.
