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...
