Well, anyone trying to write an ADD who is asking how to get OS2.H is out
of his league.  If you seriously want to write an ADD, then you need to buy
the OS/2 Device Driver Kit (DDK), which is available as an add-on
subscription to the OS/2 Developer Connection (DevCon).  The DDK includes
docs, specs, and source for most of the common ADDs which ship with OS/2,
including IBM1S506.ADD, IBM1FLPY.ADD, and so on.

There are facilities in the standard parallel port drivers for OS/2 which
allow disabling and taking them over from another driver, such as an ADD
that accesses a parallel port SCSI controller.  However, ADD programming is
probably the most difficult and complicate kind of programming you can do
on the OS/2 platform, maybe in a dead heat with file system drivers.
