<p>The TCP and UDP sockets that you know and love. Some representation
issues:
<ul>
<li>Internet addresses are represented by vectors of (unsigned-byte 8) -
viz. #(127 0 0 1). Ports are just integers: 6010. No conversion
between network- and host-order data is needed from the user of this
package.
<li>Socket addresses are represented by the two values for address and
port, so for example, (socket-connect s #(192 168 1 1) 80).
</ul>
