how to determine if a device is being throttled using the old etherios cloud connector

We are using the old Etherios device cloud connector, the one downloaded from the sample code in the support site.

Currently the number of devices we manage is growing so, now we are experiencing high latency, we assume it is because of the throttling limits inherent to the service, but we want to determine if that is the case; instead of only raise the ‘service busy’ error code.

Can we do that with the old cloud connector?
