HI,everybody!


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: http://www.kynix.com/Parts/3231833/RS232.html)

But thewireless 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 aforementioned purposes to ignore these lines in my design?


Thanks in advance!

COnnect RTS of device1 to CTS of device 2
Connect CTS of device 1 to RTS of device 2
Device one puts RTS on and waits for CTS to be active before sending
