property HalfDuplex : Boolean
Default: False
Determines whether local data is echoed to the terminal display.
If HalfDuplex is False (the default), data entered at the local keyboard is displayed only if the remote host computer echoes it back.
If HalfDuplex is True, data entered at the local keyboard is automatically displayed in the terminal window. If the host computer is echoing the input data back, each character is displayed twice.
