It is a change of protocol. I tried to get it up with NML for the first time 
yesterday but are a little bit unsure the start procedure, there are several 
programs run at startup. I simplified the linuxcnc start script yesterday to 
hardcoded format so I could figure which commands are run at startup.

Happen to know if I could use halcmd or other to check if server is up and 
running? On the client do I only need to run axis?
