I wanted to test some serial commands to my Anthem D2 through Hyperterminal. It has been a very long time since I used this software and I feel lost. I'm sure I set the parameters correctly, but all I get is a blinking cursor. I set the D2 to TX ON and I can see the commands echoed to the Hyperterminal screen as I press the remote buttons. But I can't send it a command. Any suggestions would be appreciated.
