I'm trying to talk to a Sirius tuner (SCH2P) using rs232, but need to control it using 2 different control systems (Pronto & NetStreams). I realize a simple Y-cable won't work, and did some forum searching on here to get some ideas.

The two devices some people mentioned are the XOVP14 Expansion Module from Xantech and the 9PMDS splitter from B&B Electronics. Both of these posts were made over a year ago, though.

Are there any newer products on the market? Or do you all still use these two products, and are they reliable? Thanks for any insight you could give me.
