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

# Building 
## On Linux
sudo apt-get install -y alsa-oss oss-compat build-essential autoconf libao-dev libtool libportaudio-dev portaudio19-dev
make 

### On Raspi (GPIO Interface)
Follow: http://wiringpi.com/download-and-install/
make raspi


## On OSX
brew install portaudio
make

# Hardware interface options
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).
