[vdr] Safer diseqc setup ?

I also have problems with 4 quad LNBs on a diseqc switch (1.0 and another
2.0)
If I plug out the cable from the card and plug it back again (reset switch
and LNBs)
I can use szap to change the channels. I believe the quad LNBs have diseqc
switch
 inside and at reset they are in backward compatible mode (Tone/Voltage).
In Diseqc specifications/recommendations they recommend the diseqc LNB
should ignore responding
to Tone/Voltage commands when they receive one diseqc command.
Unfortunately, I did not find the proper diseqc commands for the LNBs.

I will try today a workaround to reset the LNB before sending the
diseqc.conf sequence in backward compatible mode:
- switch to another LNB (hope the power will be cut for the one I need for
the channel)
- do the sequence for current channel
t v [E0 10 38 FF]  W500 (switch to LNB4 and wait 500) [E0 10 38 F0] W100 A
W15 t (switch to LNB1, wait for power to stabilize, use back compatible)

If I am lucky enough the switch will cut the power for the LNB1 when I
switch to LNB4.

Does anybody knows the Diseqc commands for Quad LNBs??

Thanks,
Ilariu
