Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an embedded-system device. The embedded-system device emulates a first serial port at the embedded-system device. The embedded-system device exposes the first serial port to a host of the embedded-system device through a USB connection. The embedded-system device receives first command or data from the host through the first serial port. The embedded-system device processes the first command or data.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a control system. The control system includes, a BMC managing a host computer, the BMC including a first processor and BMC firmware executed on the first processor, is to monitor temperature readings of a plurality of temperature sensors of the host computer. The control system further includes a thermal watchdog temperature sensor installed at a predetermined location of a host computer and monitoring a working temperature at the predetermined location of the host computer. The control system includes a thermal watchdog module dedicated for the host computer, independent of the BMC firmware, and in communication with the thermal watchdog temperature sensor through a communications link. The thermal watchdog module is configured to retrieve a temperature reading of the thermal watchdog temperature sensor through the communications link.

Abstract: Aspects of the present disclosure relate to a control system. In certain embodiments, the control system includes: a thermal watchdog temperature sensor, and a thermal watchdog module. The thermal watchdog temperature sensor is installed at a predetermined location of a host computer and monitoring a working temperature at the predetermined location of the host computer. The thermal watchdog module is independent of a baseboard management controller (BMC) firmware of the host computer, and the thermal watchdog module is in communication with the thermal watchdog temperature sensor through a communications link.
