It is my first time here so I apologise for my mistakes,
I started a new project where I am using Nexys 3 board with a Pmod GPS module.
I found a UART receiver/transmitter on the internet I wanted to test it out. So I connected the receiver to the USB UART Rx pin, in order to send from Serial COM data and then transmit back to the Serial COM the data I have sent. When I am sending a character from the serial, I receive the same character from the UART transmitter so I think that both of the components work fine. When I am sending the character A, I receive back the character A
