Serial, /dev/ttyS0 the data is coming in but I can't see it..
When I run "cat /dev/ttyS0" (serial) on one terminal, and then try "echo helo > /dev/ttyS0" from another terminal, i get no output from the first terminal.
However when i do this: "cat /proc/tty/driver/serial" I can see the data coming in on TX... any ideas what is wrong or where i can start looking? It just seems like /dev/ttyS0 is not working.
Any help appreciated. Thanks.
