well, i am having some issues with my inspiron 2500 and was wondering if there was any way i can test the comm1 port on the back of my laptop??? i need this to work in order to datalog my standalone. Ive done datalogging before and its always worked, but im using a different system now and wanna make sure that its software related and not my comm1 port that stopped working all of a sudden. ---

assuming its windows, i would uninstall the com1 port, then let windows find it again. If it shows up in device manager, its probably working right. Maybe try another cable if you have one? ---

Why don’t you just bring your laptop over, and I will test it for you. Check your PMs, you’ve got one from me. ---

Many usb to serial adapters are pieces of shit. There are few that work well. You can test a serial port by using hyperterminal. You just have to jumper the transmit n receive pins in the cable
