telnet <ip> VU<enter> #win!
I’m a hacker, developer and lazy guy. So when I found myself in the kitchen cooking, just realizing that my Pioneer VSX 921 receiver was turned down too low I didn’t walk over to turn it up or find the remote; I instead remembered that it has a bad app for iOS, meaning that it accepts being controlled remote over the network. A little bit of google searching and I found a plugin for an I-dont-know-what containing an XML with some Lua code (XML with code — yay), and also a very nice mapping table for commands the same code runs against a VSX 1021.
So a quick telnet session later I had yanked the volume up without ever leaving the kitchen! These commands probably work for most of the VSX 921/1021 series and later. Enjoy:
If you want to change input to the iPod port and turn up the volume, given you’re using OS X or some Unix derivative, you would do this:
There is a tone of other commands you can use, I believe this manual for the VSX 1120 is very much valid for other devices in the series.
