How to use RealTerm with keil and stm32f4-Discovery

Hi everyone, 

I've an stm32f4-Discovery kit and I'm trying to implement USART on it

Now I've installed realterm, and I have my USB-to-TTL converter module.. its picture is in the attachments.. and I'm using Windows 7 .. using KEIL uV4 

the question is.. how to use them ?

I think that I have to connect PC6 pin on the discovery board with RXI pin on the module and PC7 pin on the discovery kit with TXO pin on the module and the 5V pin on the kit with VCC pin on the module and finally GND pin on the kit with GND pin on the module, then I expect to see the output and send the input of the USART on realterm ... 

Am I right ??

Are there special configurations I've to adjust on RealTerm to make it work properly ??please help me.. thanks in advance

'' I just checked, the STM32F4Discovery board : http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF252419 Has a

STM32F407VG

The datasheet for it : http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00037051.pdf Under the pin out section PC6 and PC7 do not have USART as Alternate Function output. You MUST pick IO pins that list USART IO as part of the alternate function in order to use that USART. ''

Am I right ??''

No ''Are there special configurations I've to adjust on RealTerm to make it work properly ??'' The problem is what you have chosen to use in the STM32.
