[ECOS] Half Duplex RS485

Hi All,
My project has RS485 half duplex driven by UART0 of an LPC2112.
At present I've modified pc_serial_start_xmit and pc_serial_stop_xmit to
change a pin state so that the same wires can be used for transmit and

This does not see to work when the FIFO is enabled.
Has anyone else done RS485 half duplex?
Did you modify these routines or write your own?
Did you get the FIFO to work?

Thanks			...Laurie:{)
