Fw: TI-H: TI-85 Serial Link Problem




My link cable does the exact same thing, it slows the calc down to a crawl,
but it isn't permanent. For example I send files to my calc(s) by running
the graph link program and selecting send, at this point the program gives
me an error of not finding the calc, but, that also clears the link so that
the calc starts to act normally and when I press the send button again, the
prog finds the calc and everything works perfectly.
