50g

Question for Matthew:

From your post I'm gathering that you have successfully sent a
character string from your 50g to an active cell in an open Excel
file, or to the insertion point in some other file.

I'm having trouble following what you did to get there.

When I open the input form for APPS, I/O functions..., Transfer...,
the fields that I see in the input form don't appear to support input
corresponding to "8N1 19k baud Xon/off". I also can't find any
reference to "hyperterminal" anywhere in the three PDF manuals that
supply most of my comic relief.

I must be truly lost. My first suspicion (smack me with the cold fish
of the obvious here) is that I'm trying to get the 50g to talk to the
PC using the USB port and cable, when I should be using the serial
port and a serial cable of some kind.

If, in the input form, I choose Port: Serial,
I do see a Baud: field (which I had earlier stumbled upon using the
BAUD command). So I have a faint whiff of (maybe) picking up your
trail. But I can't fathom how to squish the rest of "8N1 19k baud
Xon/off" into this input form, nor what physical connection you are
using between 50g and PC.

All of my previous experience of HP calculator I/O has been via two
fingers and the occasional calculator dope-slap against my forehead.
Could you drop a couple of loaf-sized breadcrumbs to lead me in the
right direction?
