Heartbeat through serial ports
I have some questions. If anyone can answer at least one or point me to some documentation, it would be greatly appreciated.
I want to setup heartbeat through two computers.
Would it be better to do it through serial or ethernet?
Is listening to /dev/ttyS0 and redirecting the output to a file the only way to write to a file through serial connection?
Can you get heartbeat programs?
I have googling for the last couple days without much luck.
