There are no drivers written for Elan 2 way communication with any available Sirius recievers. There are Sirius recievers with serial control.
Antex makes a 3 tuner Sirius reciver (which is basically the same as the Elan XM three tuner ) that has a published serial protocol. (it may even be the same or very similar to the Elan XMR3) It is possible to get the driver written for this product, it will just take finding someone to do it.
I just looked, and there is a oneway serial driver already written for the Antex Sirius reciever. At this point it doesn't look like a two way driver is available, but the existing XMR3 driver MAY work, or it may not. Either way, at least one way control is available.
