[En-Nut-Discussion] UART-Polling

[Martin Walda]

Hello,

I use an Ethernut 2.1 Rev B Board with an ATMega 128 controller.

My question is, how can I poll data from the uart interface? I have tried fread, fgets and _read. All these functions seems to wait for incomming character's. I am searching for a non blocking function.

Thank you very much

Martin
