It¡¯s the same [it¡¯s fun to stay at the] YNCA protocol over both 232 and IP. I use module for the RX-A810 (or 820 or whatever it is, it¡¯s from the marketplace) because it has more inputs, including the HDMI inputs you¡¯ll need for those new AVRs. Tbh though if you ever find a command is missing you can simply edit the module and just add a signal to the Serial IO symbol (and the argument defs respectively). That¡¯s why I like YNCA, you can pretty much guess the command string needed just by looking at the other commands.
