I found it here:
http://stackoverflow.com/questions/15449017/wxmaxima-compare-logical-expressions

I also tried to first give the command
load("logic.mac");
But the package was not found, so I hoped it would be a standard part of 
Maxima meanwhile. Can you tell me how to install it?
I guess it is on this page:
https://github.com/andrejv/discrete.mac/blob/master/logic.mac

But I don't know the install instructions


thanks in advance
