I'm kind of newbie to the 50g (and hp calculators in general, for that
matter), but am kind of psyched about messing around with HPGCC as I
already know C/C++ fairly well.
Anyway, my question, which may have already been answered some time
ago (can't find any straight answers though, so) is what are the
limitations of the onboard communications on the 50g? I know the
calculator can use Kermit and XMODEM, and that pretty spectacular
things have been done so far (Usinagaz). I'm interested in using
either the RS232 serial port or the USB port to connect to other
devices and ultimately collect data from them or control them, i.e. a
PLC, a USB ethernet adapter, surveying equipment, etc. I'm not at all
interested in using IrDA.
I read another thread saying something about the calculator being a
USB peripheral which apparently poses some limitations that I'm not
seeing, as I thought the 50g can both send and receive (through all
three IrDA, USB and RS232). Anyway, thanks in advance for any
pertinent information on this subject.
Cheers, Jake
P.S. If I've been too vague about the kind of things I'm wanting to do
here, the article Egan posted a few days back about controlling an XP
computer using the serial port through SerialKeys (http://
www.sense.net/~egan/skb/) is right up my alley.
