                First left character
                It corresponds to the "call type" and it has the following
                values if available (other values may be added later):
                0 for public network "outgoing call"
                1 for "transfer" of public network outgoing call
                  followed by the transferring extension number

        Five last right characters
        Except for transfer and booth call affectation, they
        corresponds to the right justified "acting extension" (if
        available) from where the call is placed, if it is different
        from the "charged extension" in field 3 (substitution; room
        extension if management on GPIN; booth; S0 data on
        associated extension...).
        Later, when the "guest number" and "extension number"
        fields will be extended to 8 characters, that field part will
        also be extended to the same value.

        Field 9: "trunk group number" or "business code"
        The "business code" is not used in this release, so
        this field corresponds to the "trunk group
        number" (if available).

        Field 10: "number called" is left justified.
        The called number may include :
          "*" and "#" characters

        Identical to the command sent from the computer.
        Only used in case of computer problem.

        It is important to avoid to issue simultaneously two commands for
        the same GPIN or room extension on both directions.

        5.3 - (MODIFICATION)
        --------------------
        (54 + 4 characters) from PABX to computer

        Same remarks as for check-in.
        The deposit field corresponds to the remaining deposit
        (balance).

        5.4 - (CHECK-OUT)
        -----------------
        (6 + 4 characters) from PABX to computer
        Same remarks as for check-in.

        5.5 - GUEST TELEPHONE ACCOUNT

        In response to a hotel computer query, the PABX outputs for
        the corresponding guest :

        - "T" for guest Telephone account message identification

        - GPIN* or room extension** (5 characters)

        - Communications: number of effective outside calls (4
          characters)

        - Cost: total expense (8 characters plus one floating
          point).

        - Total of "deposits": (8 characters plus one floating point)
          corresponding to the original (or reset) amount plus the
          added values.

        - The guest balance (8 characters plus one floating point)
          The first character of guest balance is a "-", if the deposit
          has not been enough.

        * only if GPIN management
        **only if room extension management

        5.6 -ROOM STATUS CHANGE
        -----------------------
        Alternative with the message Datatransfer, with a Systemparameter
        it is possible to switch between the 3 type of the datatranfer.
        Two types (1 and 2) are used in the message ROMM STATUS CHANGE and
        the type 0 select the message DATA TRANSFER.

        The message includes :

        - "C" for room status Change message identification

        - Room extension (5 characters)

        - Maid identification code (4 characters)

          The hotel management may choose upon installation from
          0 (no identification code) to 4 characters to be used.

        - The new status of the room (1 character)

          . 0 the room has been cleaned and is ready
          . 1 the room must be cleaned for a new guest

        The PABX sends the "Room Status change" dialled by the maid, the
        maintenance staff or the maid inspector.

        Room Status Change Type 1:

          The maididentification code holds 4 digit
          0000 ... 0999
          1000 ... 1999 possible

          The Parameter status is one space

        Room Status Change Type 2:

          The maididentification code holds 3 digit plus one space
          000  ... 999  possible

              Extension

        This message allows to transmit to the Front Office Computer
        any information dialled from a room set or from a room set
        (Roomstate, Minibar, TV commands, list of stolen or broken
        materials.....).

        It may also be automatically generated to transfer some PABX
        data or specific event information to the computer.
        (Wakeup)

        - "P" for PABX data transfer message identification

        - Extension number (5 characters) corresponding to the
          room number or the room service number from where the
          data are dialled.

        - Code dialled :
          1 to 5 characters corresponding to the dialled code which
          indicates which kind of data is transmitted (for example
          one prefix for minibar data, one prefix for TV
          commands...).
          Those prefixes have to be chosen upon PABX
          initialisation
          In case of connecting to 4200 E PABX this field is fixed to
          the string "4200 ", to indicate the type of the PABX

        - Dialled data (20 left justified characters)
          The "#" character is reserved for immediate issue of data
          transfer.
          On 4200 E only 4 digits are possible.
          The first digit dialed of the datacode can only be "0" or "1".
          The remaining digits can be any from "000" to "999".

        This message is sent from the PABX to the computer within 30
        seconds to answer any request from the computer.

        - to answer to a request for "Password".
          The PABX returns the "Password".
        - to accept a command with a restrictive warning
        - to refuse a command with the reason

        If the previous computer command has been handled correctly,
        and if information or warnings are not necessary, the PABX does
        also send a "reply".

        If several messages have been received, the PABX sends the
        corresponding "Reply messages" in exactly the same order.

        "GPIN* or room extension" field: (5 characters)

              - If the computer asks for a specific "GPIN" which is not
                available, already given or not existing, the PABX sends a
                "Reply message" and refuses the command.

        "password" field : (4 characters)

              - A "Reply" message with a "guest password" is sent by the
                PABX upon reception of a "Check-in" message with
                "    " as "guest password".

              - A "Reply" message with a new "guest password" is sent by
                the PABX upon reception of a "Modification" message
                with "-   " as "guest password". The previous password
                for this guest, if any, is erased.

              - Values:
                "value" "   0" to "9999" proposed on computer request a "Reply"
                message with the new "guest password" is sent by the PABX. Only
                the PABX can issue a "guest Password".

                "INVb" invalid, already given or non significative

              - The"guest password" is unique for guest, so two guests
                sharing the same room cannot have the same password.
                Sharing a room is not used on 4200 E.

                - If the guest number is not agreed, the guest password
                field is not verified (non significative).

        "Status " field : (2 Characters)

                The first status character indicates the "action ":

                I Reply to Check In, and execute
                J Refuse Check In

        6 - MESSAGES SENT FROM COMPUTER TO PABX
        ---------------------------------------

        The messages described below, are sent only if the computer
        handles the corresponding function. For example, some small hotel
        "P.C." uses only the "Interrogation" message because they are
        unable to store SMDR and sometimes, to handle "Check-in",
        "Check-out" and "Modification" commands.
        If some fields are not handled by the computer, they must be filled
        with blank (ASCII space) characters.

        - "A" for guest Arrival (check-in) message identification.
              . For management on GPIN, the "CHECK-IN" is
                generally followed by an allocation command, to
                allocate a room to the guest*.

        - GPIN* or room extension** (5 characters)

        - Multi-occupation code** (1 character) not used on 4200 E

                The guest last name is limited to a maximum of 16 left
                justified characters.
                On 4200 E the 8 left justified characters are used.

                The character policy corresponds to "ISO 8859-1" (or
                "ISO Latin-1") with lower cases, upper cases and most
                of its specific characters (see table in annex 2). Specific
                characters (from A0 to FF) are only available with "8
                bits" character link transmission.
                It is possible to send the guest first name by including
                a "blank character" (space). Then the part before that
                character corresponds to the guest last name and the
                part after that character corresponds to the guest first
                name. The maximum of useful left justified characters,
                including the blank, is 16.

                On 4200 E if a password is given from the computer that
                means "change the password". Only the PABX can issue
                a password.

                "ISO Latin-1") with lower cases, upper cases and most
                of its specific characters (see table in annex 2). Specific
                characters (from A0 to FF) are only available with "8
                bits" character link transmission.
                It is possible to send the guest first name by including
                a "blank character" (space). Then the part before that
                character corresponds to the guest last name and the
                part after that character corresponds to the guest first
                name. The maximum of useful left justified characters,
                including the blank, is 16.

        ANNEX 1
        -------

        Example of CRC calculation
        --------------------------

        For the following message :
        |STX|D| |3|9|5|6|crc1|crc2|ETX|
        crc1 = 6 (36h) and crc2= D (44h).

        6Dh is the result of xor calculation on the following bytes:

        44h, 20h, 33h, 39h, 35h, 36h.

        0100 0100 xor 0010 0000 = 0110 0100 (44h xor 20h = 64h)
        0110 0100 xor 0011 0011 = 0101 0111 (64h xor 33h = 57h)
        0101 0111 xor 0011 1001 = 0110 1110 (57h xor 39h = 6Eh)
        0110 1110 xor 0011 0101 = 0101 1011 (6Eh xor 35h = 5Bh)
        0101 1011 xor 0011 0110 = 0110 1101 (5Bh xor 36h = 6Dh)

        This result is then splitted into the 2 two ASCII
        characters 6 (36h) and D (44h).
