4.4.3 Serial Communication

Library files included with Dynamic C provide a full range of serial communications sup-

port. The RS232.LIB library provides a set of circular-buffer-based serial functions. The

PACKET.LIB library provides packet-based serial functions where packets can be delim-

ited 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 transmit-

ting or receiving, and nonblocking functions, which must be called repeatedly until they

are finished. For more information, see the Dynamic C Function Reference Manual and

Technical Note 213, Rabbit Serial Port Software.

The following function calls are specific to the BL2000.

User interface to set up BL2000 serial communication lines. Call this function after serXOpen().

If Mode 1 is selected, CTS/RTS flow control is exercised using the

serCflowcontrolOn() and

serCflowcontrolOff() functions from the RS232.LIB library.

PARAMETER

mode is the defined serial port configuration.

RETURN VALUE

0 if valid mode, 1 if not.
