# What is IRMC?
|
||
IRMC stands for Internet Relay Morse Code. It implements the CWCom protocol
|
||
|
||
## 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.
|
||
|
||
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/)).
|
||
|
||
|
||
# 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)
|
||
|
||
### Serial Drivers
|
||
TBD: Driver: serial - 2usb!
|
||
|
||
|
||
# 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´
|
||
|
||

> 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.
