From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 Description of problem: Hi there None of the components listed, have to do with my problem, so far i think. I have two FC4 Servers with same configuration. They should communicate over a serial cable, that is plugged into /dev/ttyS0. If i do host A: echo "sometext" > /dev/ttyS0 i should receive the text on Host B with cat < /dev/ttyS0 But there is no text. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: HOST A echo "sometext" > /dev/ttyS0 HOST B cat < /dev/ttyS0 Actual Results: Nothing Expected Results: The text should have reached the other Host (B) Additional info: Both Servers are HP ProLiant DL120's with 2.4Ghz CPU, 1GB Memory
This is a kernel issue. Changed component for now, should resolve later today after I confirm a few things.
This works fine here with the current kernel. Check your cabling, and be sure you've actually plugged it into ttyS0. It sounds like a hardware problem to me.
