Are you not speaking of BSD4.2 talk (a.k.a Sun talk?).  BSD4.3 talk
has no such problems.

I can talk between 68K Suns, Sparc Suns, Sequents (i386), Vaxen,
Mipsen, Ultrix Mipsen etc. no problem with 4.3 talk.

MIPS chips can be big-endian or little-endian.  Ultrix makes them
little endian (like the VAX) and MIPS makes them big-endian.
