50g

Howdy All. Yep I set hyperterminal to "8N1 19k baud Xon/off" and the
program works as advertised. You have to be sure and set these
parameters in the "APPS" i/o functions transfer section and leave it
set to Kermit.
I have a newbie question (the 50g is my first HP calc ever) How do I
pass characters that the calc recognizes as operators with out a
syntax error? Characters such as +*? . Say I wanted to transmit the
string "*IDN?" This would cause a GPIB device to return its identity.
Regards
Matthew
