I am trying to use minicom to communicate with an ESP8266 Wifi chip using AT commands. I log into minicom and I type command "AT". The normal answer of the chip would be to send "OK" back to minicom. However, after typing "AT", once I type "Enter" the cursor goes back to the beginning of the line and nothing happens. It is as though the command had not been sent.
I log into minicom with
sudo chmod a+rwx /dev/ttyUSB0
sudo minicom -D /dev/ttyUSB0 -b 115200
In the Arduino IDE Serial Monitor, I am able to communicate with the chip by setting baud = 115200 and "Both NL & CR". When sending command "AT", the chip sends back answer "OK". I am trying to reproduce the same in minicom.
Any idea why the command doesn't get sent ?
Update
I saw in many minicom tutorials that command prompt cmd> should appear. Yet it does not appear on my screen. Maybe this is an indication that minicom is only in "listening" mode, and not in "waiting for command from the user" mode ?

Moving the OP answer to an actual answer:
Ok so the trick seems to be to type a command in minicom, then type Enter, then type CTRL+J.
I found the following tip in the ESP8266 datasheet (tip related to the same issue in utility screen):
Unfortunately the updated firmware versions require
Carriage-Return-and-New-Line line endings and there appears to be no
way to configurescreento send both with one key press. Instead, you
need to press or Ctrl-M then follow that with Ctrl-J.
In other words, the ESP8266 expects to see CR-NL after each command. When typing "Enter" in the minicom window, it sends character Carriage-Return (CR). This is why my cursor goes back to the beginning of the line. Then by typing Ctrl-J, it sends the New-Line (NL) character. The cursor moves to the next line and the ESP8622 understands the instruction, thus sending back "OK" to minicom.
I still do not see the cmd> prompt in minicom, but this is not an issue... Maybe this prompt does not appear in all versions of minicom (I am using 2.7).
