This might actually be the most common setup, as it is very easy to 
build[1] with minimal soldering skills and has also been used by various 
vendors (older models of the TechniSat SkyStar2 DVB-S budget card, to name 
just one example; it is only slowly being replaced by alternative means, 
as serial ports are becoming rare on newer systems.
