HP49G+ connections
Kickaha
Now that Christmas is coming I started to think to buy one of the new 49g+
(probably from Eric Rechlin of hpcalc.org, who assured me he can ship
worldwide).
I have a pair of questions regarding comunications that I'd like to know:
1- Can 2 HP49G+ communicate? I mean, with a usb-usb cable? Or only with IR?
2- Can a HP49G+ and a HP48G communicate via IR?
3- Can I connect the HP49G+ to the pc and receive and send file? I've readed
that the HP49G+ can not act as a server: it means I can't upload files
created on my calculator to my pc (that's a pity if you do some calc
programming)?
4- Can I achieve the task on point 3 using a simple usb->serial cable?
For sure I'll wait until a new official ROM (or an unofficial one, but I
strongly hope hp don't discontinue the product support after only 3 months
from launching it :oD) will be released fixing BIG bugs as earthquakes,
battery life (better than now it's possible?) and possibily IR range (or it
depends only on the hardware?).

not greater than 3cm

No it can't. Only IrDA and Red-Eye (The printer protocol) are supported
by the hardware.

Of course you can...
You just put the calculator in server mode (the new conn4x is using the
Xmodem server) and you can grab whatever files you want from your
calculator. It's really fast. Even the ARCHIVE/RESTORE command can use
xmodem now..

No. At least not with adapter you find on the market. Current USB-Serial
adaptor convert a USB host port into a serial port. Not a usb client
port (like the one on the 49G+)

I can confirm that. Eric is very fast and friendly too. In less than ten
days I got mine in Italy, at a modest price, much cheaper than here even
including shipping costs (well, the fact that the EUR / US$ exchange is
currently very good helps).

3cm? To me it seems that the calcs should be to close to comunicate. Is
something wanted for the US. examinations or simply the new CPU has a high
"power-cost" and the batteries couldn't spend more for the IR?

That's a pity. Do you think it will be possible to implement this via
software?

Ok, it is good to hear.

I imagined that... anyway, maybe via software?
Thx for your answers
