50g

I'm new to 50g, but a long-time HP user. 

It seems to me that one of the more obvious advantages of connecting a 
calculator to a PC would be the ability to use the calculator as an 
enhanced numeric keypad. I often perform calculations on a calculator, 
and then enter the result into the active cell of a PC Excel file that 
I'm working on.

A few manufacturers have offered devices that combine rudimentary (4-
banger) calculator capabilities with a numeric keypad.  These devices 
allow the user to perform a calculation, then press a button to send 
the result as a string to the insertion point in an open file on the 
PC.  These devices generally suffer from a paucity of calculation 
features.

I'm wondering whether it's possible to get the 50g to send data to the 
PC in the same way that these weakling devices do it.  Maybe I'm 
missing something obvious in the 50g documentation. Any thoughts? 

Thanks!
