Hi all,Waz here.I've hooked the tts up for the first time this morning and the problem I have is I can't select a com port.The com port panel drops down ok,I roll the mouse over and they highlite ok but I can't select one.I am using both tts cables.I am thinking I am not getting a connection between ECU and computer,any thoughts??Have I got a dud cable or something else maybe.Any input would be greatly appreciated.Thanks.. ,
