Okay,

most of these issues were because of the code in uart.c, which I believed to be a simple classic UART drive, actually implemented some processing of the bytes like reprinting them.

I simply removed most of the code in this file to write my own driver.

I had to do the same.
I wrote about it here on how I got 3 TX pins from the ESP using a SoftUart to write to one of them.
Look for "softuart_write".

On the ESP8266-12 with the NONOS-SDK-2.2.0, every char I send on the RX pin of the UART0 is reprinted/echoed on the TX pin.

How to disable this annoying echo ?
Thx !

(I suspected the "loopback" feature to be enabled by default, but clearing bit 14 of UART_CONF0(0) didn't help: SET_PERI_REG_MASK(UART_CONF0(0), UART_LOOPBACK); )
