Hi, Im not sure if this is where this topic belongs, if it is in the wrong place, sorry in advance. I have a ti 83 that I am trying to connect to my computer using a serial cable that I had lying around. Whenever I plug the one end into the calculator, and the other end into the serial port, my screen freezes on the calculator and the computer program cant see the calculator. Im wondering if anyone would have an idea on what is causing this. Thank you.
