>From memory if the driver loses connectivity (ie no response is received to
an API request) it retries the same command two more times and if still no
response falls back to broadcast to locate the device (the MAC address is
used to ensure the driver connects to the same device). If no response to
the broadcast then the 60 sec delayed driver restart kicks in and if an IP
address has been specified it should be used rather than using a broadcast
(need to check). I could probably have the driver try the IP address (if
one has been specified) as well as the broadcast before bailing out into
the 60 second delayed driver restart.
There is the ability to reboot the GW1000 but you need connectivity to
issue the command plus I am loathed to start doing things like that in the
driver.
