[From QnA] WIZ140SR at 115200 baud

Question

This post came from QnA of WIZnet website I’ve been testing the WIZ140SR at 115200 baud, and I’m occasionally seeing character drop-outs and noise on the line at this rate. Things seem to be much more stable at 57600 baud. I have not gone back to verify my findings on your EVB, but just wondered how confident you were we could run all 4 ports at 115200 and expect 0 dropped or corrupted characters. Thanks, Gary

Dear customer. Our product does not guarantee 100% perfect communication with serial. But we had tested serial communication and the result is that under 115200 baud rate the serial communication is stable. Try to use hardware flow control. Maybe it is useful. Thanks. WIZnet.
