    29 *  The basic client class.

    30 *  The basic client class representing a channel of communication 

    31 *  with the server. The connect function starts the server, if it 

    32 *  is not already running. An RSessionBase sends messages to the 

    33 *  server with the function RSessionBase::SendReceive(); specifying 

    34 *  an opcode (TScardServerRqst) and and array of argument pointers. 

    35 *  This class is a friend to the classes Comm and Listener.

    36 *  All four are classes that need to communicate 

    37 *  directly with the server.
