Basically it transmits a 9 bit command byte using 13v/18v levels to represent 0/1. I didn't see any reason why it wouldn't be possible to move the signalling algorithm itself into the dvb_frontend core code, where it would just call the appropriate frontend set_voltage methods. Of course, timing is very important using such a simple method - so we'll have to see. If I have a go at developing that, would someone with suitable dish networks equipment be able to test a couple of patches?
