the serial output from the calculator would be RS232. I really
appreciate you giving the heads up that it is not standard RS232
but "3.3V TTL signal (noninverted)," however I don't know the
ramifications of that difference. So I guess the question is, are the
two signals compatable and the interface as simple as building a cable,
or is there some signal incompatabilities that require additional
electronic signal processing (for example an inverter) in order to
interface the calculator to a standard RS232 connection?
