irmc - Internet Relay Morse Code

IRMC stands for Internet Relay Morse Code and is an implementation of 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. Landline telegraphs use "closed circuits" for communications; if you have built one at home, you may also use the loop interface.
