So let’s see how IC-7410 is supported by Hamlib.

% dpkg -l | grep hamlib
ii  libhamlib-dev   1.2.15.3-1ubuntu4 amd64 Development library to control radio transceivers and receivers
ii  libhamlib-utils 1.2.15.3-1ubuntu4 amd64 Utilities to support the hamlib radio control library
ii  libhamlib2      1.2.15.3-1ubuntu4 amd64 Run-time library to control radio transceivers and receivers

First, we have to download the source code from here.

% ls -l ~/Downloads/hamlib-1.2.15.3/icom/*.h

A little bit surprising, because I thought all the rig dependent definitions are in ic*.h

 % wc *.h ic7410.c

  252  1273  9525 icom.h

   65   289  2208 optoscan.h
  233   751  7880 ic7410.c

The above definitions match well with the following descriptions in the operation manual:

Now that you have the source, if anything goes wrong, it’s your fault!
