<h3><a name="slipdriver">SLIP</a></h3>
<p>
The NuttX SLIP driver supports point-to-point IP communications over a serial port.
The default data link layer for uIP is Ethernet.
If <code>CONFIG_NET_SLIP</code> is defined in the NuttX configuration file, then SLIP will be supported.
The basic differences between the SLIP and Ethernet configurations is that when SLIP is selected:
<ul>
<li>The link level header (that comes before the IP header) is omitted.</li>
<li>All MAC address processing is suppressed.</li>
<li>ARP is disabled.</li>
</ul>
If <code>CONFIG_NET_SLIP</code> is not selected, then Ethernet will be used
(there is no need to define anything special in the configuration file to use Ethernet -- it is the default).
</p>
<ul>
<li>
<code>CONFIG_NET_SLIP</code>: Enables building of the SLIP driver.
SLIP requires at least one IP protocols selected and the following additional network settings: <code>CONFIG_NET_NOINTS</code> and <code>CONFIG_NET_MULTIBUFFER</code>.
<code>CONFIG_NET_BUFSIZE</code> <i>must</i> be set to 296.
Other optional configuration settings that affect the SLIP driver: <code>CONFIG_NET_STATISTICS</code>.
Default: Ethernet.
</li>
<p>
If SLIP is selected, then the following SLIP options are available:
</p>
<li>
<code>CONFIG_CLIP_NINTERFACES</code>: Selects the number of physical SLIP interfaces to support. Default: 1
</li>
<li>
<code>CONFIG_SLIP_STACKSIZE</code>: Select the stack size of the SLIP RX and TX tasks. Default: 2048
</li>
<li>
<code>CONFIG_SLIP_DEFPRIO</code>: The priority of the SLIP RX and TX tasks. Default: 128
</li>
</li>
