4.4.3 Serial Communication
Library files included with Dynamic C provide a full range of serial communications sup-
port. The
PACKET.LIB
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.
