I do not understand how I get my 800 region free. I found some info, but where do I find the Windows Hyperterminal?

With 800 in Standby connect to the Video card RS232 port with Windows Hyperterminal:

Bits per second: 9600
Data bits: 8
Parity: None
Stop Bits: 1
Flow Control: None.

Having connected take 800 out of Standby by pressing "Open" on the Front panel then send the following commands.

%% (to enter factory mode)
%p constable (installer password)
%z 1f (region 1 free surf)
%w (to write to non-volatile area)

then disconnect.

Note: characters are echoed but not "Enter". All input overwrites line 1.
You will get a warning after "%%".
After "%w" you should get a "Settings saved" message.

Greatful for any help.
