As for a book, I highly recommend "Writing OS/2 Device Drivers" by
Raymond Westwater (this is from memory, but the author's last name is
definitely correct) -- it's 1.3 vintage, but works fine with 2.0.

I do not recommend "Writing OS/2 2.0 Device Drivers in C" by Steve
Mastriani, because it's not much use without the author's rather
expensive library.  (The code disk for the book is freely available on
CompuServe OS2DF1 -- a good place for OS/2 device driver help -- but
it doesn't include the library.)

Of course you'll want the IBM "Physical Device Driver Reference".  The
best way to get it (and a whole lot more besides) is to sign up for
the free IBM WorldWide Developers Assistance Program on CompuServe (GO
OS2DAP), and then order the $15 Professional Developers Kit CD-ROM.

Best regards,
John

p.s.  You'll need MASM to assemble your driver.
