I don't know whether it is right to ask this question here,but if anyone knows,please help me.
I'm designing a hardware containing the mbed and the WIZ610WI wireless module, and I want to connect those using a RS232 interface.(Here

some details of RS232: http://www.kynix.com/Parts/3231833/RS232.html)
But the wireless module requires a 5-wire connection, with the RTS and CTS lines, and I could not figure out how use these connections with mbed UART.
Can anybody show me a way to configure a serial port in mbed that includes RTS/CTS? Would it be fatal for the purposes metioned above to
ignore these lines in my design?

Thanks in advance!
