   A lot of MS-DOS boards began life as single node boards. Most of the   
   multi-node ideas were tacked on like a bad afterthought, since after the 386   
   arrived the capacity for mult-tasking had arrived.   
      
   To that end most inter node communication was done with semaphore files and   
   file locking.  There's no capacity to talk directly to the other node process.   
   And this is usually limited to sending a message or seeing what another node   
   is doing.   
      
   This was true of QuickBBS, Remote Access, SuperBBS and any of the other myriad   
   of clones that were around at the time.
