IO_SERIAL_RAW_IO

I am having issues with serial_translation. Base on an older post this is what I have tried.

#define RS485_SERIAL_CHANNEL "ittyb:"

MQX_FILE_PTR rs485_dev = NULL;

rs485_dev = NULL;
rs485_dev = fopen( RS485_SERIAL_CHANNEL, (pointer)IO_SERIAL_RAW_IO );

Howevery when I run this code it is still doing the serial translation!

while( fstatus(rs485_dev) == TRUE ) {
read(rs485_dev, &data, 1);

}

Any suggestions?

There is an attribute for non-blocking operation:

uartDef->uart_device = _io_fopen(uartDevicesTbl[uartIndex],
(char _PTR_)(IO_SERIAL_RAW_IO | IO_SERIAL_NON_BLOCKING));
