Hi Pilar,


What asyn driver are you using?  How does it implement the asynInt32 getBounds() method?

Hi Mark,

exactly, I'm using this variable as a bitmask. But before trying with ao
type, I used a longout having the same results as with ao.

That why I was thinking the problem should be something related to CSS.

And if you want to be able to control all 32 bits without worrying about the sign you should use the asynUInt32Digital interface, rather than asynInt32.  That ensures that the value is treated as an unsigned 32-bit number.
