====== Netradio Control ======

** Python code for TCP/IP control of multiple radios **

===== Server =====

This provides TCP/IP access to one or more radios, allowing control of Frequency, Mode, Pre-amp and Attenuator. It also gives remote access to S-meter readings.

There are separate rig-dependant command modules that then provide a standard interface for commands sent by a client, regardless of the particular radio connected.

There are modules for

  * Icom C-IV radios such as IC-R75, IC-718, IC-7200 etc.
  * AOR AR7030
  * Icom IC-M710 marine

# The protocol document states that for messages FROM the controller TO the radio
# the ECC bytes are optional, and may be omitted. This appears to be false information, and
# the ECC bytes seem to be necessary.

# The ECC checksum, is a two-digit hex value found by XORing the hex values of the characters 
# between "$" and "*" (but not including the $ or *)

# The first part of the message is always:
# "PICOA,90,01," and this has an XOR value of (decimal) 112
# we then XOR this with each character's decimal ASCII value, in the required command
# and convert the result to a 2-digit hex value
