I have started to have serial port issues. When I first start the PC, everything works, XM, HD Radio, OBD2 and AMP_CTRL. If I open anything that is serial, it will freeze after a certain amount of time. At first I thought it was CF, but then I tried Mitch's HD Radio application and after 2 minutes I tried to change the channel and his app frooze. My setup worked perfect, the only thing I can think that could be the issue is that I started to use AMP_CTRL, before I used Volume_Amp_Ctrl, could that be the issue? I also started to use a device called a PAC TR-4, its a remote trigger for all of my AMPS. http://www.buy.com/prod/pac-tr-4-low.../90129363.html. Only other thing I can think of is that the PAC TR-4 is not connected correctly. I have the green wire connected to pin 4, then it has a ground. Should I connect this ground to the ground on the serial port? currently I have it connected to my distrobution block. What else should I try to do to trouble shoot?
