Systems, methods, and devices for accessing a device operating system over an interconnect
A method for communicating with a device may include running, at a device, an operating system, communicating, using a first function of an interconnect, with the device, and communicating, using a second function of the interconnect, with the operating system. The operating system may include communication logic, and the communicating with the operating may include communicating with the communication logic. The communication logic may one or more terminal support drivers, and the communicating with the communication logic may include communicating with the one or more terminal support drivers using a terminal application. The terminal application may run on a host. The second function of the interconnect may be configured to operate with a controller. The communicating with the operating system may include communicating with the operating system based on a privilege information. The host may be a management controller. The method may further include controlling, using the second function of the interconnect, a program on the operating system.
