Hello, i have a question regarding the com ports in windows 7 Ultimate 64x.
I am trying to use a usb-obd2 cable for diagnosing a car. Now it requires a latency (msec) of 1 but here's the thing, it does not have that option in device manager. The reason the diagnostic-software is not working is because the latency is set too high, it even tells me so. I do know that other OS like windows xp does have this option under "BM options" when you navigate through properties in the chosen com port.
Is it suppose to be changed somewhere else or does Windows 7 ultimate 64x not have this option? and if not, what are my alternatives?
Any answers are appreciated. Happy regards!
