Hi friends ,I encountered a problem with serial terminal and ftdi.Let me explain.Stm32f103 is sending data to Ftdi and Ftdi is sending this data to serial terminal and I can see data, but I couldn't manage to send data to Ftdi from serial terminal.If I try with ESP8266(this is module with usb) I can send AT and I receive OK also I can see my data on terminal that I want to send ,but if I try with ftdi stm32f ,when I try to enter any key on keyboard I can see led activity on FTDI but there is no any command on terminal and stm32f doesn't receive any command from terminal.
I handled it,it was about terminal settings.I didn't know it.But when I use ESP8266 module it worked ,it has different usb to ttl converter,but no problem.I used hyperterminal file->options-settings->asci settings and show chars
