[App_rpt-users] Interfacing Motorola TRBO XPR 4350 to BeagleBoard?

I think I read someone has interfaced a TRBO XPR radio. Can you assist me with where you grabbed the TXA, RXA, COR and PTT? Did you get them off the connector on the back of the radio? I don't see the appropriate pinouts to configure as these in CPS? Thanks, Mike kb8zgl
