Citrix simulation api -output mode

Question

Hi,

I'm trying to set my output mode of the ica client to NonHeadLess before i launch it. And once launched, im trying to send it some keystroke programatically. I dont seem to be able to do it, though it works if output mode is normal. The documentation states that setting to NonHeadLess disables window management functionality. Does this include sending keystrokes too?

Thanks
