Re: streamdevice I/O Intr

How are you commanding the bo record? 
Are you sure its value is being commanded to zero when you want to stop reading?

Did you try something like, 'caput xxx:Toggle 0' ?

Hi Dirk,

thanks for the quick answer.

I have set

field(PRIO, "HIGH")

but this doesnt seem to do anything?

I have asynTraceMask on aswell but I dont see the "ETM" command ever
pass through...
