response message must be automatically forwarded to the client). Otherwise, the

See Example 3 in Requesting a One-Time Update later in this chapter for an example
of a request using this specification.
Specifying an Outgoing Application Message
The LNS DDE Server uses the following item format for sending application and
foreign frame messages:
[device_name.]msg_out[.msg_code] [parameters]
Where each component of the item format has the following meaning:
device_name
Optional. The name of an application device as defined in
the LNS database.
msg_out
Required. msg_out is a keyword, not a user-defined name.
This keyword is case insensitive.
msg_code
Optional. Specifies the message code, in decimal.
Application message codes are from 0 to 62. Foreign frame
message codes are from 64 to 78. Do not specify message
codes outside this range. If a message code is specified, the
item data contains just the message. If a message code is not
specified, then the first byte of the item data must contain
the message code.
Parameters
Optional.
The parameter options are:
-a bool
Specifies whether the message should be sent with an
authenticated service. May be set to True or False. If not
specified, the default value specified in the Messaging
Options configuration dialog is used.
This option is ignored when used with broadcast messages; it
applies only to unacknowledged or repeated service types.
-p bool
Specifies whether the message should be sent with priority
service. May be set to True or False. If not specified, the
default value specified in the Messaging Options
configuration dialog is used.
