Frame Trailer (Postamble) Flags

The Frame Trailer (Postamble) Flags field describes the trailer portion of the serial frame and the

processing

options. It is only effective in the Send_with_Response service when Framing

is enabled in the Receive Flags.

Note: The Receive Length field should be set to a value large enough for the data and

trailer portions even if the Strip option is enabled.

Frame Trailer (Postamble)

The Frame Trailer (Postamble) field contains the byte values expected at the end of a valid

serial input frame. The number of significant bytes comes from the Frame Trailer (Postamble)

Flags field.

Data

The Data field contains the bytes that will be output on the serial port. The length of this

field should equal at least the amount of data specified in Send Length, but can be longer

to simplify programming. In a Get_Attribute_Single or Send_with_Response reply it contains

the incoming serial data acquired.
