HDH(4) | NetBSD Kernel Interfaces Manual (VAX) | HDH(4) |
NOTE: At the moment, NetBSD does not support IMP, so this manual page is not relevant.
The hdh device provides an HDLC Host (HDH) interface to an IMP. It is normally used when participating in the DARPA Internet. The controller itself is not accessible to users, but instead provides the hardware support to the IMP interface described in imp(4). The configuration entry for the IMP must also include the pseudo-device as shown above in the SYNOPSIS.
Any other error message from hdh%d: indicates a serious error detected by either the driver or the IF-11/HDH firmware.
