Description
This parameter sets the number of milliseconds to
delay after RTS is asserted before the data will be
transmitted. Valid values are in the range of 0 to
65535.
This parameter sets the number of milliseconds to
delay after the last byte of data is sent before the
RTS modem signal will be set low. Valid values
are in the range of 0 to 65535.
This parameter specifies the handshaking used on
the port. The values are as follows: None=No
hardware or software handshaking, RTS/CTS
hardware handshaking, DTR/DSR hardware
handshaking and XON/XOFF software
handshaking.
This parameter is used if bit 0 of the Type
parameter is set. This value (0 to 12) defines the
number of termination characters used to define
the end of received message.
This array of 12 integer values representing the
characters used to define the termination
characters at the end of each received message.
The number of characters to be used in the array
is set in the RTermCnt parameter.
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.
