Abstract: In one embodiment, a monolithic integrated circuit includes a first UART, a second UART, and a multiplexer. The first UART has a parallel IO interface to couple to a host system to transceive parallel data and a serial IO interface. The second UART has a parallel IO interface and a serial IO interface coupled to the serial IO interface of the first UART. The first and second UARTs convert parallel data into serial data and serial data into parallel data. The multiplexer has an output coupled to the serial input of the first UART, a first input coupled to the 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 control signal selectively coupling serial interfaces of first and second UARTs together for remote terminal services at a remote computer system over a network.
