Patent ID: 8838856

Claim:
A monolithic integrated circuit comprising: a first universal asynchronous receiver transmitter (UART) having a first parallel input/output interface to couple to a host system to receive and transmit parallel data and a first serial input/output interface, the first UART to convert parallel input data into serial output data and to covert serial input data into parallel output data, a second universal asynchronous receiver transmitter (UART) having a second parallel input/output interface and a second serial input/output interface, a serial input of the second serial input/output interface coupled to a serial output of the first serial input/output interface of the first UART, the second UART to convert parallel input data into serial output data and to covert serial input data into parallel output data, a first multiplexer having an output coupled to a serial input of the first UART, a first input coupled to a serial output of the second UART, a second input coupled to a serial input of a serial communication port, and a select input coupled to a virtual UART control signal; and wherein the virtual UART control signal to selectively couple the serial input of the first UART and the serial output of the second UART together to provide remote terminal services at a remote computer system over a network.
