Error probability UART RS232

Hello everyone, Is there any way to reduce the error probability in a serial transmission using the UART provided by Altera? For a baudrate of 115200 bps there is a Pe = 0.001 (1 erronous byte ...

Hi,

I use the uart provided by altera.

The direction is from my pc sending bytes via serial port to the FPGA.

The error rate is in the received bytes of the FPGA.

Y just count when there is an error in the uart status register:

if (status & (FIFOED_AVALON_UART_STATUS_PE_MSK |

FIFOED_AVALON_UART_STATUS_FE_MSK))

{

errors++;

}
