 +After receiving and processing a QWKnet ''.QWK'' or ''.REP'' file, Synchronet will //touch// the ''[[dir:data]]/**qnet-qwk**.now'' or ''[[dir:data]]/**qnet-rep**.now'' files to trigger timed events of those names, if they exist, to execute.
  
 +==== Pause Server Semaphore File ====
 +The existence of the file ''[[dir:ctrl]]/pause'' (or a supported service/host variant) will cause that server to stop accepting incoming client connections. Any existing clients/connections will continued to be service while the server is paused. Removing the file will "resume" the server.
