I would rather characterize the situation by saying that all current 
satellite radio models have some kind of vendor specific serialized 
interface, but few are standard plug and play RS-232. You almost always 
need some form of adapter.

Also, most laptops do not have serial ports (only USB) though there are a 
number of good USB to serial port adapters.  If you are homebrewing an 
interface you can get a chip similar to 
http://www.ftdichip.com/FTModule.htm from several vendors and use a 7417 to 
drive the interface.
