Hi"
I want send data from arduino Uno ( equiped with "board USB" connected to Rx and Tx pin0 and pin1) to a Pc . the received data will be displayed by Hyperterm .
question : I want to know if I can use a "normal USB cable" or a twisted ( D+ and D- ) ?
note : I know that I can do it with the "download plug " if I stop the IDE program ...
thank's for your help
I apology :I am french...

Please provide a detailed description of what you mean by "board USB".

It's not necessary to stop the IDE. You can leave the IDE running while you are doing serial communication with Hyperterm. It is true that only one application can have the serial port open at a time. The only time the IDE has the serial port open is during uploads and when yuou have Serial Monitor or Serial Plotter open. So you do need to close the Serial Monitor or Serial Plotter before opening the port in Hyperterm. You also need to close the port in Hyperterm before uploading via the Arduino IDE.
hi,
thank you for your answer !
by " board USB " I mean small added circuit ( serial adapter Module TTL to USB ) who convert the I/O Rx and Tx ( pin0 and pin1 on mother board Arduino Uno ) . It that link I want to connect to a Pc with a USB cable . and I want to know if I must use a twisted cable ( D+ and D- ) as we do for RS232 link ( Rx and Tx twisted in the cable ) .
For the second part of your answer ( stop only the serial monitor ) it is a very good idea ! I will try it ASAP !
Thank 's 
Bruno
You can use a normal USB cable to connect the USB to TTL serial adapter module to your computer.
thank's a lot ! I will try it and I will write some news here .
