Reading arch/ppc/8xx_io/uart.c, I found out that all the flow control
related code was surrounded by false #if #endif. It seems that there is
no flow control at all on either the SMC or SCC serial ports in UART
mode. Is there a patch somewhere to implement flow control, or is it
still missing ? I was wondering what to do with CD/DTR/DSR (as Linux
only support RTS/CTS flow control for now), and had hoped to find an
answer in the source code...
