+Les Kerr released the open source software MorseKOB. He also extended the CWCom protocol for landline telegraphy

+Compatibility between the original CWCom server and the MorseKOB server is guaranteed by a relay server

+Today we have software clients for Windows, Linux, iOS and even Arduino.
+Any client can connect to any of the servers.
+Hardware interfaces for morse keys and telegraph sounders are available for serial port, USB, Raspi GPIO or bluetooth.

-## CWCom Servers
-The clients will connect to one of the servers using the CWCom protocol.

-## Compatibility 
-The original CWCom protocol has been extended for MorseKOB, as landline telegraphy uses 
-closed circuits (latching). There are mainly two server types for moip (see below):
-the original CWCom server and the MorseKOB server. Both servers are compatible using a
-relay server written by Bob Denny ([source code](https://github.com/8cH9azbsFifZ/moip-relay-server/tree/master)).
