Hence, you need press followed by Ctrl-J to send a command. Please note that most recent ESP firmwares require Carriage-Return-and-New-Line (\n\r - ASCII 10 13) line endings. The ones to try first are 9600 (it depends on the version of the firmware running onboard). First, your board might talk at any of several baud rates. For that, a terminal emulator like picocom or the standard screen command will do the job.
At this point, I wanted to start talking to the ESP.
