CME9210: RS485

Hi everybody,

This topic came up several times but up to now nobody seems to have a solution for the CME9210 with Linux.

In DigiEL 5.1 it’s possible in kernel configuration to use UART A in “RXTX485” Mode.

What else has to be done (tcsetattr() or ioctl()) that RTS drives the output enable of the rs485 transceiver by HW?

Any sample code would be great.

Thanks,
