using Quad UART

[harryweb]

Thank you for your reply.

Why does I want to use external uart with buffer ?

Please see PDF attached file.

Actually my PCB has 5 PICS.
The PIC 1 to 4 are connected to network (via tibbo modules with usart 1 and to the "master" PIC via USART2
These 4 PICS are driving RF attenuators

4 distant Network sends order to each PIC (1 to 4)
These PIC also received order from Sensitive keyboard or a local (RS232) terminal connected on the master PIC

As you can see, I need 1 USART. I MUST use SERIN2/SEROUT2 (witch are not good as hardware usart)

This is my problem

Communication are 9600 and 38400 Bds

So my idea is to use an external USART to bypass the use of SERINOUT2
