     Name
          daemon.mn - Micnet mailer daemon

     Syntax
          /usr/lib/mail/daemon.mn [-ex]

     Description
          The mailer daemon performs the ``backend'' networking
          functions of the mail, rcp, and remote commands by
          establishing and servicing the serial communication link
          between computers in a Micnet network.

          When invoked, the daemon creates multiple copies of itself,
          one copy for each serial line used in the network.  Each
          copy opens the serial line, creates a startup message for
          the LOG file, and waits for a response from the daemon at
          the other end. The startup message lists the names of the
          machines to be connected, the serial line to be used, and
          the current date and time.  If the daemon receives a correct
          response, it establishes the serial link and adds the
          message ``first handshake complete'' to the LOG file.  If
          there is no response, the daemon waits indefinitely.

          If invoked with the -x switch, the daemon records each
          transmission in the LOG file.  A transmission entry shows
          the direction of the transmission (tx for transmit, rx for
          receive), the number of bytes transmitted, the elasped time
          for the transmission (in minutes and seconds), and the time
          of day of the transmission (in hours, minutes, and seconds).
          Each entry has the form:

               direction  byte_count  elasped_time  time_of_day

          The daemon also records the date and time every hour.  The
          date and time have the same format as described for the date
          command.

          If invoked with the -e switch, the daemon records all
          transmission errors in the LOG file.  An error entry shows
          the cause of the error preceded by the name of the daemon
          subroutine which detected the error.

          The mailer daemon is normally invoked by the start option of
          the netutil command and is stopped by the stop option.

          During the normal course of execution, the mailer daemon
          uses several files in the /usr/spool/micnet/remote
          directory.  These files provide storage for LOG entries,
          commands issued by the remote(C) command, and a list of
          processes under daemon control.
