4.4.4 Serial Communication
Library files included with Dynamic C provide a full range of serial communications sup-
port. The LIB\Rabbit3000\RS232.LIB library provides a set of circular-buffer-based
serial functions. The LIB\Rabbit3000\PACKET.LIB library provides packet-based serial
functions where packets can be delimited by the 9th bit, by transmission gaps, or with
user-defined special characters. Both libraries provide blocking functions, which do not
return until they are finished transmitting or receiving, and nonblocking functions, which
must be called repeatedly until they are finished. For more information, see the Dynamic C
User’s Manual and Rabbit’s Technical Note TN213, Rabbit 2000 Serial Port Software.
Use the following function calls with the LP3500.
User interface to set up LP3500 serial communication lines. Call this function after serXOpen().
Whether you are opening one or multiple serial ports, this function must be executed after executing the last
serXOpen
function AND before you start using any of the serial ports. This function is non-reentrant.
If Mode 1 is selected, CTS/RTS flow control is exercised using the serBflowcontrolOn and
serBflowcontrolOff
functions from the RS232.LIB library.
PARAMETER
mode
is the defined serial port configuration.
RETURN VALUE
0 if valid mode, 1 if not.
