Yes, you can use Hyperterminal to communicate the serial port of the AC Pro. Set up Hyperterminal to make a direct connection to the correct serial port. Configure it for 9600 baud, no flow control, 1 stop, and no parity. Note that Hyperterminal has a bug in it that results in it not setting the baud rate correctly when it is changed. Save the session with the correct settings, and then restart that session to work around.
