*** KK7DS ID-RP* Frequency Tool ***

This is a simple tool that allows setting of the frequency parameters
on ICOM D-STAR Repeaters.  It has been tested on the following
modules:

 - ID-RP2000V and ID-RP4000V
 - ID-RP2D (the ID-RP2V is expected to work as well)

To run the tool, connect one of the repeater's SERVICE ports to a USB
port on this machine and then run the tool as root:

  # ./rpttool

WARNING: Do not connect or try to program the ID-RP2C controller
module.  This tool should be safe to use, but no guarantees are made.
The author believes that the ICOM devices are smart enough to prevent
bricking, but you're on your own if anything happens.

If you have any other devices connected that are using an FTDI
USB-to-Serial device, they must be disconnected prior to running this
tool.  The FTDI driver module will be re-loaded with a special
parameter to allow it to recognize the ICOM device.
