NOTE: This driver has not been ported from 4.4BSD yet.
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.
The hdh
driver appeared in
4.3BSD.
