Why are you messing with baud_base? Don't, unless you really know what you are doing. A normal 16550a with baud_base set to 9600 will run at 115200 when an app tries to run it at 9600. baud_base is just the quotient the serial driver uses to calculate the divisor needed to run the UART at a given speed. > > I hoped after "setting up" the serial ports with setserial some magic > would happen and they would apear in /dev/tts... but I was wrong. > > gets me working serial ports... but it's not in /dev... :O > can you not make them?
