If it works on your old computer, but not the new, then there is something
wrong with the RS232 port on the new computer, or the driver that supports
it. Whatever it is, it is intermittent, as the computer is able to
occasionally communicate with the console.
A few things to try:
1. If the computer has more than one RS232 port, try a different one.
2. Do you have a serial-to-usb converter? If so, you could use that instead.
3. Check dmesg, just to make sure the kernel isn't trying to tell you
something. Simply type "dmesg" and check the last 10-20 messages or so.
4. Perhaps your new computer has more RF noise than the old? You could try
some ferrite coils around the serial cable.
5. Finally, it is conceivable that your new computer has an odd default
configuration for serial ports. To see what it is using, try this:
*stty -a -F /dev/ttyS0*
(From the log, it looks like you're using /dev/ttyS0, but substitute as
necessary.)
Configuring serial ports is an ancient black art with its roots in the
1970s and I don't pretend to be an expert.
