In case you didn't read it too closely, my last couple versions of my serial comms script included -- and relied on --
TTY timeouts. If any serial read hung it would just die after a configurable number of tenths of a second.
Reading from /var/log/messages sounds like a very poor solution. For one thing, it could break from changing the configuration of your system logger and isn't likely to work on a system where it differs even slightly. For another thing this means your serial communications program probably needs root access to work!
