Re: Auto tap No conflicts, it just says "No Auto Tap module found". This is the first time on this computer, but I know the port works because I use it at work.

Re: Auto tap I believe the AT1 is powered from the PC serial port so both DTR and RTS pins are held high by the Autotap software. If these pins are not working properly the com port may still function properly for other applications (that do not use these pins) but AT1 interface will not power up.
Just a wild guess <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

All of the autotap's take their power from the vehicle. If you have a blown fuse, this may cause a loss of power on the OBDII port.

I do believe early model AT1 interfaces did use the RTS/DTR lines for power.
I develop software for them and found that to be the case.
However, I just tested a later model interface and it appears to work fine without the DTR and RTS lines.
