Why on earth does a generic (I hope) protocol driver (some ISDN
thingy in this case) care about endianess at all?

Or has things come to a "the world's an x86" ("the world's a VAX" for
old-timers but add 25+ years or so) situation where the majority of
coders don't even consider that machines might be different from what
they use? If so, a deep sigh of sadness.

(Not that I prefer a particular endianess. My point being that coders
shouldn't make endianess assumptions unless they're really^3 important.)>
