Process Signals Relevant to the Operation of TekNap                           

TekNap's behavior can be controlled (to an extent) from the Unix command line
via signals.  The following signals have notable affects on the client:

   SIGTERM   cause the client to immediately, but gracefully, exit
   SIGKILL   cause the client to die immediately, no cleanup
   SIGUSR1   cause the client to close all DCC connections and any EXEC'd
             processes that are still active. a hook SIGUSR1 is processed at
	     as well.

Typically, these signals are delivered with kill(1).  The client's process
id (PID) must be known to send it a signal.  The PID may be obtained with the
ps(1) command, or other utilities that display running processes.  The basic
form would be:

   % kill -USR1 <PID>
