RS-232 flow control on an RS-232 port is initiated in software using the

function call from

RS232.LIB

trol lines are specified using a set of five macros.

SERX_RTS_PORT—Data register for the parallel port that the RTS line is on (e.g., PCDR).

SERA_RTS_SHADOW—Shadow register for the RTS line's parallel port (e.g., PCDRShadow).

SERA_RTS_BIT—The bit number for the RTS line.

SERA_CTS_PORT—Data register for the parallel port that the CTS line is on (e.g., PCDRShadow).

SERA_CTS_BIT—The bit number for the CTS line.

Standard 3-wire RS-232 communication using Serial Ports C and D is illustrated in the following

sample code.

#define CINBUFSIZE

#define COUTBUFSIZE 15

#define DINBUFSIZE

#define DOUTBUFSIZE 15

#define MYBAUD 115200

#endif

main(){

serCopen(_MYBAUD);

serDopen(_MYBAUD);

serCwrFlush();

serCrdFlush();

serDwrFlush();

serDrdFlush();

serCclose(_MYBAUD);

serDclose(_MYBAUD);

}
