        !            10: DESCRIPTION    dpd___
        !            11: is the 201 data phone daemon.
        !            12: It is designed to submit jobs to
        !            13: the Honeywell 6070 computer via the gerts
        !            14: interface.
        !            15: .sp
        !            16: dpd___ uses the directory /usr/dpd________.
        !            17: The file lock____ in that directory is used
        !            18: to prevent two daemons from becoming active.
        !            19: After the daemon has successfully set the lock,
        !            20: it forks and the main path exits, thus
        !            21: spawning the daemon.
        !            22: /usr/dpd________ is scanned for any file
        !            23: beginning with df__.
        !            24: Each such file is submitted as a job.
        !            25: Each line of a job file must begin with a key
        !            26: character to specify what to do with the remainder
        !            27: of the line

        !            29: .in +3
        !            30: S_ directs dpd to generate a unique snumb card.
        !            31: This card is generated by incrementing the first
        !            32: word of the file /usr/dpd/snumb______________
        !            33: and converting that to decimal concatenated with
        !            34: the station ID.
        !            35: .sp
        !            36: L_ specifies that the remainder of the line is to
        !            37: be sent as a literal.
        !            38: .sp
        !            39: B_ specifies that the rest of the line
        !            40: is a file name. That file is to
        !            41: be sent as binary cards.
        !            42: .sp
        !            43: F_ is the same as B_ except a form feed is prepended to the file.
        !            44: .sp
        !            45: U_ specifies that the rest of the line
        !            46: is a file name.
        !            47: After the job has been transmitted,
        !            48: the file is unlinked.

        !            51: Any error encountered will cause the daemon to
        !            52: drop the call, wait up to 20 minutes and start over.
        !            53: This means that an improperly constructed
        !            54: df__ file may cause the same job to be submitted
        !            55: every 20 minutes.
        !            56: .sp
        !            57: While waiting, the
        !            58: daemon checks to
        !            59: see that the lock____ file still exists.
        !            60: If the lock____ is gone, the
        !            61: daemon will exit.
