Now you may add any kind of framing skins or whatsoever.

Keep in mind that the application might not be aware of and for example still assume a 24x80 screen, even if you took some characters off for a beautiful frame. Last but not least, every program opening CON on its own will as well bypass your driver. Don't forget to make the driver as well handling read requests, as Command. Com requires both ways to go thru the same device.

Device drivers can be a lot of fun and are usually way less complicated to write then people tend to assume. Caveat: Some mechanics only work with DOS 3. Just they can only be source or destination. On the down side, you'd have to rewrite all of it's functionality - hopefully compatible with ANSI. SYS which already is one.
