Folks,

 

Jueri Tagger from BNL says the asynPortDriver::readInt16Array method in asyn R4-44-1 is not working for him.  He says the readInt16Array method is not being called when the associated waveform record processes.

 

It works fine for me in the asyn testErrorsApp test program.

 

This is dbpr on my waveform record:

I notice that on his record the MLIS,SPVT, and STAT fields are <nil> whereas that is not the case for my record.

 

Is this an indication of a problem like perhaps memory corruption in his driver, or can that be normal?

 

Thanks,

Mark
