# What is IRMC?
|
||||
IRMC stands for Internet Relay Morse Code. It implements the [CWCom protocol](http://kob.sdf.org/morsekob/docs/cwcom.pdf) as adopted by [MorseKOB](http://kob.sdf.org/morsekob/docs/history.pdf). You can try out the software in a [browser](http://kob.sdf.org/morsekob/morsekob30/index.htm) using Java.
|
||||
|
||||
## Why morse code over IP?
|
||||
Why not? A number of different approaches for CW over IP exist. An early implementation has been the CWCom protocol,
|
||||
which has been the basis for Morse KOB, a ready-to-use software. Both chat programs have been written for CW exclusively and are compatible. An alternative implementation in C exists as well as a port to the ATMEL AVR Microcontroller.

=== Original post ===
|
||||
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.
|
||||
|
||||
Bugs
|
||||
There are a few that I am working on right now, but feel free to send me feedback if you get a chance to try it out.

|
||||
Besides a variety of other approaches exist, for example an IRC plugin ([CWirc](http://myspace.voo.be/pcoupard/cwirc/)), a [JavaScript implementation](http://morsecode.me), a [bandwidth-eating UDP implementation](http://hans.liss.pp.se/node/343), a [chat for iOS](http://pignology.net/cwwithme.html) or a modulated CW over IP using Mumble ([iCW](https://sites.google.com/site/icwoip/)).

The following people have helped me a lot to learn the protocols and setting up test servers.

# 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
|
||||
```
|
||||
>>>>>>> master
|
||||
|
||||

|
||||
=== End Original Post ===
|
||||
## 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".
|
||||
|
||||
|
||||
# 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´
|
||||
|
||||
## Morse KOB Servers
|
||||
* faeroes.sdf.org 7890
|
||||
* mtc-kob.dyndns.org 7890
|
||||
A current list of servers if provided on the [MorseKOB Website](http://mtc-kob.dyndns.org).
|
||||
|
||||
## 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).
