It is their job to transmit and receive frames on the physical network medium. VxWorks includes three different classes of data link layer drivers: the Ethernet drivers; the Serial Line Interface Protocol (SLIP) driver; and the shared-memory network driver, which provides communication over a backplane. VxWorks also supports the creation of custom interface drivers. </p></dl></dl><a name="foot"><hr></a><p class="navbar" align="right"><a href="index.html"><img border="0" alt="[Contents]" src="icons/contents.gif"></a><a href="c-dll.html"><img border="0" alt="[Index]" src="icons/index.gif"></a><a href="c-dll.html"><img border="0" alt="[Top]" src="icons/top.gif"></a><a href="c-dll.html"><img border="0" alt="[Prev]" src="icons/prev.gif"></a><a href="c-dll2.html"><img border="0" alt="[Next]" src="icons/next.gif"></a></p></body></html><!---by WRS Documentation (), Wind River Systems, Inc. conversion tool: Quadralay WebWorks Publisher 4.0.11 template: CSS Template, Jan 1998 - Jefro --->⌨️ 快捷键说明
