[IGSTK-Developers] Loopback test

[Luis Ibanez]

Hi Patrick,

The page that you posted has the instructions on how to
set the Flow Control. It is in the "properties" option of
the Hyperterminal connection.

Please look at the following image:

from the same site that you posted.


    Regards,


     Luis
