MoIP - Morse over IP
In analogy to voice over ip (voip) we can also do morse code over ip (moip). A number of different approaches for CW over IP exist. Here we describe the well-establised CWCom protocol. Besides a variety of other approaches exist, for example an IRC plugin (CWirc), a JavaScript implementation, a bandwidth-eating UDP implementation, a chat for iOS or a modulated CW over IP using Mumble (iCW).
CWCom Protocol
A number of different approaches for CW over IP exist. An early implementation has been the CWCom protocolCWCom, John Samin (VK1EME): http://www.mrx.com.au/d_cwcom.htm, which has been the basis for Morse KOBMorse KOB, Less Kerr: http://kob.sdf.org/morsekob/ Morse KOB 4.0, Less Kerr: https://sites.google.com/site/morsekob/, a ready-to-use software.

An alternative implementation in C exists as well as a port to the ATMEL AVR Microcontroller.

What is IRMC?
IRMC stands for Internet Relay Morse Code. It implements the CWCom protocol as adopted by MorseKOB. You can try out the software in a browser using Java.
