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