Once you access the stick via ssh you will be presented with a second tier login. The credentials to access the zyxel shell are: username: `twmanu` , password: `twmanu`.
From the Zyxel shell you can move to a standard Linux shell using the `linuxshell` command
+## Serial
+
+The stick has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface. It's near the SFP header. TX, RX and ground pads need to be connected to a USB2TTL adapter supporting a logic level of 3.3V.
