i have a ti-89 calculator, and i've bought a linking cable to join my computer to it. little did i know how flaky the connections were. i'd transfer maybe a file or two (over usb) and it would just stop until i reconnected my usb cable and tried again.
being fed up with this i did some research. i believe that the problem lies in the calculator's receiving ability. i think it may time some things wrong and the usb calls just pass right by it until i reconnect it.
there is another way to transfer files, but there's only software for calculator to calculator transfer. i want to replicate that connection from computer to calculator, because for some reason on the calculators that connection has never failed.
if you're completely confused at this point i'll just ask this question. how hard is it to write programming that sends signals to and from the calculator via the usb port? there is linux source code for a ti-89 usb driver, which i can check for reference. (too bad it doesn't compile...)
and one final question: am i wasting my time?
