I've added the 'console=' parameter to my lilo.conf file. I've tried several iterations such as 'console=ttys0','console=cua0','console=ttys0,9600n8', etc.... They all fail to produce any output to the serial port although they do remove the text from my screen. When I have booted RedHat I can type 'echo blah > /dev/cua0' and I see text output from the serial port. Interestingly when I try to echo to /dev/ttys0 I get an IO error message. I'm using a null modem cable connect to a windows machine to watch the serial port. My question: why can I see output when booted into RedHat but not when booting the OS? I've read that you have to compile this feature into the kernel. Does anyone know if RedHat's kernel come with this feature built in?
