RS485 Programming

Oct 18, 2005 4:29AM PDT

I don't know linux very well how do I setup SCC3 and SCC4 to give out a baud rate of 128000 and 256000 bits per second respectively. I'm using a MPC860, the function i'm using is:
int __init rs_8xx_init(void)

How do I program values into BRG, and connect to the channels. Then set up the I/O(program the ports as outputs, initialize values). Change SCC RS232-->RS485 mode. ASYNC-->SYNC
