The registration port.

This is a deprecated method for controlling (bringing up and down) ACM 

functions.

ACM Class Controllers open a registration port and use SetSignalsToMark and 

SetSignalsToSpace to bring ACM functions up and down.

The newer method involved creating a session on the ACM server (RAcmServer) 

and using the APIs provided.
