hyperterminal to pic

i hooked up a rs-485 from a pc to a pic...
so heres the order...


pc > rs232 to rs485 converter > rs485 > pic


the main objective is for the USART of the pic to communicate with hyperterminal.... using the rs485 was to make sure that longer communication was possible..

how do i initiate the usart?

Reading the documentation for your PIC might help... There are hundreds of examples on how to use a PIC's Uart, Nigel's website would be one place for ASM code. Google will net you many pages of information.

It is similar to PIC to PC communication for RS232.

But you need to tell the rs485 driver when to switch between send and receive.
