  Routine: main (server.exe)
 
  Purpose: Main routine for MIDAS server process. If called one
           parameter, it listens for a connection under
           MIDAS_TCP_PORT. If a connection is requested, the action
           depends on the parameter:
 
           0: Single process server: This process executes RPC calls
              even if there are several connections.
 
           1: Multi thread server (only Windows NT): For each conn-
              ection, a seperate thread is started which servers this
              connection.
 
           2: Multi process server (Not MS-DOS):  For each conn-
              ection, a seperate subprocess is started which servers 
              this connection. The subprocess is again server.exe, now
              with four parameters: the IP address of the calling 
              host, the two port numbers used by the calling
              host and optionally the name of the experiment to connect
              to. With this information it calles back the client.
 
           This technique is necessary since the usual fork() doesn't
           work on some of the supported systems.
 
  Input:
    int  argc               Number of parameters in command line
    char **argv             Command line parameters:
 
                            ip-addr     callback address as longword
                            port-no     port number
                            program     program name as string
                            experiment  experiment name as string
 
 
  Output:
    none
 
  Function value:
    BM_SUCCESS              Successful completion
