Doubt about the Serial port Arduino

Thanks for your responses. I need use two serial ports for to see the datas that I send to this ports :slight_smile: I solved this problem.

I have another problem with serial port..... for example when I use delay() function I have problems to receive datas from serial port. I send for TX0 a specific data and , later, I use delay() function for wait another data that will arrive from RX0. If I use delay() function I have very problems with the serial interrupt (I think that If I wait by delay() function the program is blocked in this point). How can I solve this problem?

Thanks :slight_smile: :slight_smile:

This is my program (the specifications are in spanish...sorry).
