;  $VER: magplip.i 1.2 (20 Aug 1995)
;
;  magplip.device - Parallel Line Internet Protocol
;
;  Original code written by Oliver Wagner and Michael Balzer.
;
;  This version has been completely reworked by Marius Gröger, introducing
;  slight protocol changes. The new source is a lot better organized and
;  maintainable.
;
;  Additional changes and code cleanup by Jan Kratochvil and Martin Mares.
;  The new source is significantly faster and yet better maintainable.
