Linux serial console over AMT SOL - in practical way
One of hidden gem and underrated in AMT is Serial-Over-LAN (SOL). For most Unix veterans, embedded developers and Telco equipment/IT admins, managing devices using serial port is common rite. We occasionally connect serial port over modem for remote access. Sometimes we hook it to Serial over IP box so that it is reachable within enterprise. AMT Serial-Over-LAN brings this communication port to the next level. With AMT, Serial-Over-LAN boundary now expands with the connection tunnel established by AMT (either local network or across the internet using CIRA). For most AMT capable system or vPro certified platform, the chipset will expose a serial port which is managed by Manageability Engine. This device can be used by locally running software to communicate with remote party. The remote party can connect to this serial port using AMT SOL Redirection protocol. So, how do you find out which serial port is AMT SOL in Linux? A simple dmesg will list ttyS recognized by Linux kerne
