Query: "Electronics Today" treatment of the subject

Relatively complete treatment of the basic Centronics and Bi-directional modes. About 5 pages devoted to EPP and ECP--nothing about protocols or support from any (modern) operating system. All examples use Bios calls which are unavailable after DOS. Looks like a re-tread of a much earlier work. Hardware-software examples are fine, but utilize many parts which have been out-of date for years. A real disapointment..I sent it back!
