FE_DISEQC_SLAVE_REPLY can tell you whether it supports 1x or 2x Diseqc 1.0 is 22k tone burst with controlling 4 committed switches Diseqc 1.1 is Diseqc 1.0 + transmission of upto 2 repeats Diseqc 1.2 is Diseqc 1.1 + positioner commands Diseqc 2.0 is control 4 committed switches, readback and one repeat AFAIK, all devices that do support 1.1 also support 1.2 as well. Or are there any devices that are different ?
