Checkpoint on Nokia was famous for having these problems, while vrrp was able to reach the interface and therefore it was alive, the checkpoint application its self was dead (nothing new for Checkpoint there!) and no action taken.

While I agree the assumption of a down may be weak, it has yet to fail me in this instance. Checkpoint had buggy software.

There is a serial port module in CPAN that allows you to control a serial port.
