simSerialOpen

Opens a serial port (RS-232) for communication. When called from a script, the function can only be called when the simulation is running (and in that case the port is automatically closed at simulation stop)

C++ synopsis

int simSerialOpen(char* portString, int baudRate, void* reserved1, void* reserved2)

Arguments

• portString: string specifying the port to open. Under Windows, use something similar to "\\.\COM1". Under MacOS and Linux, use something similar to "/dev/*" (check the "/dev" folder to know what file to specify). Under Linux, you might have to launch CoppeliaSim with super user priviledges in order to access the serial port.
• baudRate: baudrate
• reserved1: reserved for future extension. Keep at nullptr.
• reserved2: reserved for future extension. Keep at nullptr.

Return

• -1 if operation was not successful, otherwise a port handle
