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?
## Install dependency: morse keyer library
```
wget https://github.com/8cH9azbsFifZ/morse/archive/v0.1.tar.gz
tar xzf v0.1.tar.gz
cd morse-0.1
libtoolize
./autogen.sh
./configure  --with-portaudio
make
sudo make install
```

## Debian (Wheezy)
Some dependencies have to be installed:
```
apt-get install -y alsa-oss oss-compat build-essential autoconf libao-dev libtool
```
Afterwards compilation with `make` should work. If something went wrong, you may have
to adjust your `LD_LIBRARY_PATH`. Alternatively try:
```
LD_LIBRARY_PATH=/usr/local/lib ./irmc mtc-kob.dyndns.org 7890 33 123 
```

## OSX (Yosemite)
Compilation with make :)

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/)).

# 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).
