Com at 4800,7,e

[pautax]

Hi, i have to receive ASCII data with arduino 1 from a device rs232 that send data at 4800 baud, 7 bit, parity even.
How to setup com port ?
How to detect parity errors ?
many thanks

How to detect parity errors ?

Look if help:

Arduino error detection by PARITY check

GolamMostafa: @OP It appears from your original post that your are receiving text message over UART Port which is asynchronous serial protocol, and it supports only 'parity bit' for data validity check. You may choose one of the following options for 'parity' check bit; but, you have to write codes yourself to take advantage of it. Serial.begin(speed, config) Parameters Serial: serial port object. speed: in bits per second (baud) - long config: sets data, parity, and stop bits. Valid v…

I think you have to write your own HardwareSerial handler. I believe the Arduino runtime ignores parity, framing, and overflow errors. Framing error: "The stop bits were not HIGH". Overflow error: "A new character came in while all of the hardware buffers were full."
