I am starting with UART communication in PIC32MX795F512l
. This UART will communicate with PC. I was just wondering that it is important to connect RTS
& CTS
or just connecting Rx Tx GND will make the communication? Some websites say RTS & CTS are also important but some say that its not important. I am really confused. Please help.!

RTS & CTS are not always important. You can directly make cross connections like
Rx -> Tx
Tx -> Rx
GND -> GND
