Whistler Remote Control Demo 2.1
================================

WHAT THIS IS
------------
"Whistler Remote Control Demo Program" (ControlDemo.exe, published as
ControlDemo2.1.exe), copyright 2014-2017 Whistler Group, built 2017-07-18. It
demonstrates the remote-control protocol that the WS and TRX radios speak over
their USB serial port: sending key presses and commands and reading the
display, as documented in Whistler's Remote Control Protocol document (v1.6 on
Whistler's pages; v1.7, published 1 August 2017, is in the Reference Library).
The June 2017 firmware round added current-channel information to that
protocol.

Whistler also offered it zipped (ControlDemo2.1.zip, uploaded 2024-05-10); the
executable inside is identical to this one.

APPLIES TO
----------
Whistler WS1080, WS1088, WS1095, WS1098, TRX-1, TRX-2, TRX-1E, TRX-2E, and GRE
PSR-800, RadioShack PRO-18 and PRO-668 radios after the Whistler Official
Upgrade (Whistler's legacy page listed it). The protocol features available
depend on the radio's firmware.

BEFORE STARTING
---------------
- A Windows PC with the model's USB serial driver installed and the COM port
  number known.
- Close EZ-Scan (only one program can hold the COM port).

INSTALLATION
------------
No installer: run ControlDemo2.1.exe, select the scanner's COM port and use
the on-screen controls. The program's screens were not documented by Whistler
and were not verified here.

VERIFYING
---------
The program shows data from the radio (display text, status) once the correct
COM port is open.

IF SOMETHING GOES WRONG
-----------------------
- Port errors: another program has the COM port, or the driver is missing.
- Features that do nothing: the radio's firmware predates the protocol command
  (for example, Get Active Channel arrived with the June 2017 firmware).

DOWNGRADING
-----------
Only version 2.1 was found; nothing to downgrade.
