To start using the terminal emulator, plug the 
EasyFlash3 cartridge to your C64, turn your C64 on 
and connect your Mac to your EF3 with USB. 
Perhaps try chmod 700 ef3irc. 
Then run: 
./ef3irc

See http://skoe.de/easyflash/doku.php?id=driver for instructions 
if you want to run ef3irc without being a root. 
Else add sudo to the recipe above.
