Note that the typical scenario for uart(4) to not respect the baud rate setting is when the UART port is a system device (i.e. serial console or debug port). Make sure there's no difference between 8.x and 9.x with respect to which ports are declared as system ports. FYI, -- Marcel Moolenaar marcel@xcllnt.net
