Description
This parameter is used if bit 3 is set in the Type
parameter. The parameter sets the length of data
required to be received on the port before
transferring the data to the processor.
This parameter is used if bit 1 is set in the Type
parameter. The parameter sets the number of
milliseconds to wait after the first character is
received on the port before automatically sending
the data to the processor.
This parameter is used if bit 2 is set in the Type
parameter. The parameter sets the number of
milliseconds to wait between each character
received on the port before sending the data to
the processor.
This parameter specifies if the data received
should have its bytes swapped before sending
over the backplane.
This parameter specifies the timeout period to
transmit a message out the port. A message must
be transmitted out the port within the specified
timeout period. Message transmission will be
aborted if the timeout is exceeded.
This parameter specifies the minimum number of
milliseconds to delay before transmitting a
message out the port. This pre-send delay is
applied before the RTS on time. This may be
required when communicating with slow devices.
This parameter specifies if the data to be
transmitted out the port will have the bytes
swapped from the data presented across the
backplane.
