This is my first project and I need to design a RS232 DB-9F port for it. This is my understanding of what I need to do. Correct me if I am wrong!!
So I need UART RS232 full handshake. Since FULL HANDSHAKE requires all DB9 pins except RI and DCD, that leaves me with 6 connections between a RS232 voltage-converter IC and DB9 pin. That means 3 pins for receiving (CTS,RX,DSR) and 3 for transmitting (RTS, TX,DTR). That means i need a RS232 voltage-converter IC with 3/3 Driver/Receiver.
Is this all I need, or did I miss something?
