DDN(4) | NetBSD Kernel Interfaces Manual (VAX) | DDN(4) |
The ddn device provides a DDN Standard Mode X.25 interface to an IMP using the ACC ACP625 X.25 board. It is normally used for connecting to the Defense Data Network (DDN). The controller itself is not accessible to users, but instead provides a network interface for the Internet Protocol described in ip(4).
Any other error message from ‘ddn%d:' indicates a serious error detected by either the driver or the ACP625 firmware.
