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.

The good (bad?) news about this notoriously documented multiplex interrupt is that it is going to be used more and more! +-------------------+-----------------------------------------+ | Glenn Wallace | Net: drift@qut.edu.au | | Drift Project | Fone: +61 7 837-7126 Fax: +61 7 221-0173| | Telecom Australia | Snail: 11th Flr 144 Edward St., | +-------------------+ Brisbane, Q4000 Australia | | | | Disclaimer - The opinions expressed must be my own, because | | Telecom is a statuatory authority and as such, | | is not capable of having opinions. | +-------------------------------------------------------------+

Too bad that the SDK docu has no information A description of the purpose of INT 2F and how it is to be used can be found in the DOS technical reference manual.
