4.5 Serial Communication Calls
Library files included with Dynamic C provide a full range of serial communications support.
The RS232.LIB library provides a set of circular-buffer-based serial functions. The
PACKET.LIB
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 receiv-
ing, 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 2000 Serial Port Software.
Use the following function calls with the Smart Star.
