irmc - Internet Relay Morse Code
|
||
================================
|
||
|
||
IRMC stands for Internet Relay Morse Code and is an implementation of [MOIP](https://github.com/8cH9azbsFifZ/moip).
|
||
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.
|
||
|
||
|
||
|
||
|
||
# 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
|
||
./irmc morsecode.dyndns.org 7890 2348 test
|
||
|
||
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 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:
|
||
Serial PIN: 4 & 6

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