Solution 1

htons() is your friend. And portable. It converts from the byte order of the host to a a network formatted short.

There's an htonl if you ever need to do the same thing with 32 bit data.

Solution 2

When transmitting data over a network, you should use host-to-net functions to make sure you always send it in a systematic way. Look here htons()[^] and here ntohs()[^] to get it back again.
