 irmc - Internet Relay Morse Code
 ================================
-
 IRMC stands for Internet Relay Morse Code and is an implementation of [MOIP](http://8ch9azbsfifz.github.io/moip/).
 
 # How to build?

 For the USB serial devices you need a PL2303 driver 
 (i.e. [PL2303_Serial-USB_on_OSX_Lion.pkg](http://changux.co/osx-installer-to-pl2303-serial-usb-on-osx-lio/)).

-Or you may want to use tcpdump, i.e.:
-```
-sudo tcpdump -i all -vvvv "host faeroes.sdf.org"

 A good description on how to build different interfaces (telegraph key, sounder or both) 
 is given on the [MorseKOB Website](http://kob.sdf.org/morsekob/interface.htm). 
 Landline telegraphs use "closed circuits" for communications; if you have built one at home, 
 you may also use the [loop interface](http://kob.sdf.org/morsekob/docs/loopinterface.pdf).
