The goal for these patches is to improve the default > hardware flow control handling and also add CTS/RTS support for SCIFA/SCIFB. The serial core expects RTS pin control to be implemented via the driver's set_mctrl() method, and will take care of raising and lowering it when necessary. Regards, Peter Hurley
