Like this (https://arduino.stackexchange.com/questions/24578/how-to-filter-a-blank-line-received-over-serial-esp8266)? It sounds like the firmware on the chip is written incorrectly. If it is doing something like echoing lines back with \r\n at the end you can usually configure your terminal software to translate them to \n, but if it's doing it sporadically you may need to put a layer in between you and the terminal. > With Arduino devices I had no problem to do the same thing with > gnu-screen like this > > screen /dev/ttyUSB1 115200 > > ...with the ESP8266 (using the same baudrate as with cutecom > before) the cursor get glued in the upper left corner. > Hitting a key, CTRL-D.

I tend to use it above anything else because it is sufficient and I am generally working with Python. There is no readline support, but you didn't ask about that. Importantly it doesn't cook the input in any way or expect the terminal to do anything, so you can use it to better figure out what the ESP8266 firmware is doing. Cheers, R0b0t1
