# 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/)).
## Testing with MorseKOB 3.0 (Java)
This [software](http://kob.sdf.org/morsekob/morsekob30/MorseKOB.jar) will run on
Linux, Windows and OSX. With the [RXTX software](http://morsekob.org/morsekob30/help.htm)
for Java (i.e. [librxtxSerial.jnilib](http://blog.brianhemeryck.me/installing-rxtx-on-mac-os-mountain-lion/) on OSX) it is even possible to connect to external hardware.
NB: before you transmit make sure you uncheck the "circuit closer".
Or you may want to use tcpdump, i.e.:
```
sudo tcpdump -i all -vvvv "host faeroes.sdf.org"
```
# How to use:
The usage is: `irmc [hostname] [port] [channel] [id] [serialport`
For example:
`./irmc mtc-kob.dyndns.org 7890 103 MyID /dev/tty.usbserial´

## Hardware interface options
A good description on how to build differnt 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).

Connecting the palm radio: keep an eye on the grounding :)

> I have been using cwcom to practice sending morsecode, unfortunately my main computer at home is running openbsd and it has gotten harder to gain access to a reliable MS Windows machine. So I wrote my own client that works on openbsd.
> This is written in C and although not tested it should compile under other OS. If any one wants to try it and send me feedback. you can download version 0.01 here http://fernan.bitbucket.org/irmc.tgz
> Les Kerr of https://home.comcast.net/~morsekob/ has been very patient in answering my questions regarding the cwcom protocol and setting up a test server during debugging.
>
> There are few difference between this and the official cwcom client
> 1. It is a command line tool
> 2. It does not send the characters of the message to the receivers screen.
> 3. It does not translate CW for you. You can try fldigi if you just want see the transmission.
> 4. Tone pitch is currently hard coded to 650Hz
> 5. It does not have a way to show you who is listening.
