When I press a key on a remote which has not been learnt by flirc = sign is sent by flirc, in other words if I use my TV remote when my PC is on with flirc plugged in I hear an error sound from my PC and if I have a text editor open = is typed also if the flirc program is open on the keyboard page I can see that the = keyboard key is being pressed. This happens with any remote that hasn't been used for flirc.
