How to use CTS/RTS lines with a RS232 interface?


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 are
some details of RS232:
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

Can anybody show me a way to configure a serial port in mbed that
includes RTS/CTS? Would it be fatal for the aforementioned purposes to
ignore these lines in my design?

Thanks in advance!
