The serial port will be configured as RS232 if 0 is provided as argument , will be configured as RS422 if 1 is provided as argument and will be configured as RS485 if 2 is given as argument.

...

ERRPARAMS errparams;  // structure for returning error code and error string
BYTE mode,port;

...

// To configure serial port as RS232

mode = 0; // 0- RS232, 1-RS422, 2-RS485
port = 0; // 0 - Serial Port pair 1 and 2 , 1 - Serial port pair 3 and 4

if(DSCSAM_SerialPortConfig(mode,port) != DE_NONE)
{
    DSCGetLastError ( &errparams );
    printf ( "DSCSAM_SerialPortConfig error: %s %s\n", DSCGetErrorString ( errparams.ErrCode ), errparams.errstring );
    return 0;
