The IOIO indeed has 4 UARTs that can be used concurrently. The voltage levels are logic-level, so if you want RS232 voltage levels, you'd need to use level shifters, such as the MAX232 family. For future reference, this is the IOIO bible: https://github.com/ytai/ioio/wiki Specifically, you'd have found your answer on the UART page.
