Use the TELL prefix to identify the executor node for a particular NCP
 command.   TELL sets the executor for only one command and must prefix
 the command for  which  it  is  intended.   This  command  allows  you
 optionally  to  specify access control information in one of two ways:
 as part of the node-spec or as distinct parameters.

 TELL    node-spec       ACCOUNT account
                         PASSWORD password
                         USER user-id

 All underscores found in parameters must be replaced with spaces
 when parameters are used in NCP commands.
