[time-nuts] prologix device as sniffer

[Prologix]

Patrick,

Sorry the product didn't work out for you. With the current firmware, there
is really no good way to do what you want to do. GPIB bus sniffing is an
oft-requested feature that we will certainly consider adding in the future.
Email me off-line if you wish to return the unit.

Regards,
Abdul

Thanks Abdul

This comes as a pretty big blow, as this is what I was hoping to do with 
it from the start.

Is there a way to set it up to read one address continuously?

thanks in advance-Patrick
