This is a function for opening the flange serial transfer port in the robot controller.
This command is not available in the new flange version (v2).

Definition
DRFLEx.h within class CDRFLEx, public section (line 876)

bool flange_serial_open(
    int nPort,
    int baudrate = 115200,
    BYTE_SIZE eByteSize = BYTE_SIZE_EIGHTBITS,
    PARITY_CHECK eParity = PARITY_CHECK_NONE,
    STOP_BITS eStopBits = STOPBITS_ONE)
{
    return _flange_serial_open(_rbtCtrl, nPort, baudrate, eByteSize, eParity, eStopBits);
};

Parameter

Parameter Name	Data Type	Default Value	Description
baudrate	int	115200	Baudrate setting for serial communication. Supported values: 2400, 4800, 9600, 19200, 38400, 57600, 115200, etc.
nPort	int		Serial port index 0: x1 1: x2
eByteSize	BYTE_SIZE	BYTE_SIZE_EIGHTBITS	Data bit length
eParity	PARITY_CHECK	PARITY_CHECK_NONE	Parity configuration
eStopBits	STOP_BITS	STOPBITS_ONE	Stop bit configuration

Return

Value	Description
0	Error — failed to open serial port.
1	Success — serial port successfully opened.

Example

Drfl.flange_serial_open(115200, 0);

Drfl.flange_serial_write(0, "test123");

LPFLANGE_SER_BD_PARAM temp = Drfl.flange_serial_read(4, 5);
cout << "Serial read S = " << temp->_pSnd << endl;
cout << "Serial read R = " << (int)temp->_iSize << endl;

Drfl.flange_serial_close(0);

This example opens the flange serial port (channel 0) at 115200 baud, sends a test string, reads back a response buffer, and closes the serial connection.
