Hi, Sherryl,

It still doesn't work. That's what I've got.

--------------------------------------------------------
>> daqregister('parallel')

ans =

'mwparallel.dll' successfully registered.

>> DIO=digitalio('parallel','lpt1')
??? Error using ==> digitalio.digitalio at 93
Error using ==> 
digitalio.digitalio>localCreateDigitalIOObject at 187
Failure to open requested data acquisition device.
---------------------------------------------------------

That happens in two toshiba laptops(one A45 and one A20). 
In the desktops, there is no problem! 

Thank you!
