Absolutely. Such techniques have been used for 150 years, using lamps or reflected sunlight to send Morse-like codes to human observers. Consumer computer applications date back at least 20 years, such as the Timex Datalink watch. As a practical matter, this is the same task as interpreting a 1D barcode, such as a UPC label. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
