3 This is an interesting errno. the Single Unix Specification defines it as being 'Reserved', and gives no further help. The Linux source uses it in a few places for what appears to be networking related (eg: the network card has no link). Man pages around the Internet imply that it's a filesystem error -- the file could not be found because a link to the remote host is down.

9 * A usb network device loses its network link.

12 Perhaps the distinction is in setting up a connection versus sending data over a previously established connection that has failed? -- JohnMcPherson
