I have some doubts this works correctly in all cases. When a buffer has been filled on the device side and is requested by libsigrok, the whole buffer has to be fetched. There is no SCPI method to request e.g. only the first 50k samples, AFAIK. If you stop reading after 50k samples and the device has prepared 500k samples, the remainder will be returned as response to the next command. --- > The second version (v2) of this patch introduced the support for 16 > digital (logic) channels for the following oscilloscope models: HMO3032, > HMO3042, HMO3052 and HMO3522 (previously only 8 digital channels were > supported, i.e. only 1 POD). This change is not related to the original patch and does not fit the subject.

This change is also not related to the original patch and does not fit the subject.
