What device is the serial port on the netwinder?
I tried to open both /dev/ttyS0 and /dev/ttyS1 and perror generated the message “/dev/ttyS0: Operation not supported by device”. In order to activate the serial port, you need to install the serial module by executing “insmod serial”. In later kernels, the serial driver is compiled in by default. This allows you to redirect all kernel messages to the serial port, so the NetWinder can be used without a monitor attached.
