First Claim
1. An information handling system comprising:
- a service connector operable to receive an RS-232 signal and a Universal Serial Bus (USB) signal, wherein the service connector comprises a USB type connector;
a voltage converter operable to convert the RS-232 signal from a first voltage level to a first serial signal at a second voltage level when a signal received by the service connector is the RS-232 signal;
a protocol converter operable to convert the USB signal to a second serial signal at the second voltage level when the signal received by the service connector is the USB signal; and
a universal asynchronous receiver/transmitter (UART) operable to receive the first serial signal and the second serial signal.

Abstract
An information handling system includes a service connector operable to receive an RS-232 signal and a USB signal. The service connector is a USB type connector. The information handling system also includes a voltage converter operable to convert the RS-232 signal from a first voltage level to a first serial signal at a second voltage level when a signal received by the service connector is the RS-232 signal, a protocol converter operable to convert the USB signal to a second serial signal at the second voltage level when the signal received by the service connector is the USB signal, and a UART operable to receive the first serial signal and the second serial signal.

9. A method comprising:
-
receiving, at a service connector of an information handling system, a first signal, wherein the service connector comprises a Universal Serial Bus (USB) type connector; determining that the first signal is an RS-232 signal; in response to determining that the first signal is an RS-232 signal; providing the RS-232 signal to a voltage converter operable to convert the RS-232 signal from a first voltage level to a second signal at a second voltage level; and providing the second signal to a universal asynchronous receiver/transmitter (UART); and in response to determining that the first signal is a USB signal; providing the USB signal to a protocol converter operable to convert the USB signal to a third signal at the second voltage level; and providing the third signal to the UART. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
