Hi,

I found several remarks on that mysterious usage of int 2F
to perform various tasks, e.g. establish a communication
between DOS and Windows at interrupt level. 
I read about documentation of these calls in the DDK.
Is there another reference which contains a good description
of int 2F and it's usage/parameters or am I supposed to
buy the DDK ?  Too bad that the SDK docu has no information
on this (as well as they omitted the WinOldApp-interface info).

Thanks, Martin.
