@Johannes: behave.

The required delays, the number of required message repetitions depend on the 
actual setup. The old-fashioned API was not able to handle anything but 
simple non-cascaded switches.

Please check the DiSEqC spec for details.

?!?

Not without removing the ability to be DiSEqC 2.x compliant and to support 
anything else beside the standard single-switch, unidirectional DiSEqC 1.0 
setup.

Those changes have been introduced about 2 years ago, proper rotor support and 
support for cascaded DiSEqC devices would never have been possible without. 
Bidirectional DiSEqC support neither.

Can you please explain a little more in detail what exactly is your problem 
and why it never showed up before?

Holger
