Some of the fields in packet headers are byte order sensitive; the data must be sent in high-to-low order. ``Byte order'' illustrates this.
You must account for this byte order when writing an
application that communicates with an unknown machine type.
if an application running on an Intel® 80386
CPU does a t_sndudata,
the data portion of the IPX packet is sent
over the wire in 80386 (low-to-high) order.
This presents a problem if the receiving CPU
(for example, a Motorola® 68030) does not use the same
low-to-high byte order.
