Use Uno to UART program another device

HI! I have been away for a long time. I have a new project now, and to start, I need to program a HC05 BT module. I remember that since I have no MAX232 chip, that I need a way to UART to the module and send AT commands thru the terminal. I know I recall a sketch for the Uno that will do a passthrough of sorts and let me communicate with the BT module, but I can't find any reference to it in my searches. Any ideas?
