control and assignment of multiple operator terminals (IPC, thin client):
Number of VNC clients
Status of focus assignment
Name of the active VNC client (master)
List of VNC clients
Individual name of a VNC client from the client list
Constraints:
Call only from a submit/spawn job
If no name is configured for a client, its MAC address is returned in the PLC
strings.
Mode 3/4: The sequence and numbering of the client list can vary from one
boot instance to the next, since this information depends on the point in
time at which the clients register themselves in the system.
