+.Tn DEC
+.Tn DMV-11
+point-to-point serial communications device
+.Sh SYNOPSIS
+.Cd "dmv0 at uba0 csr 167000 vector dmvrint dmvxint"
+.Sh DESCRIPTION
+NOTE: This driver has not been ported from
+.Bx 4.4
+yet.
+.Pp
+The
+.Nm dmv
+interface provides access to a point-to-point communications
+device which runs at up to 56 Kb/s.
+.Tn DMV-11 Ns s
+communicate
+using the
+.Tn DEC
+.Tn DDCMP
+link layer protocol.
+.Pp
+The host's address must be specified with an
+.Dv SIOCSIFADDR
+.Xr ioctl 2 ,
+and the destination address specified with a
+.Dv SIOCSIFDSTADDR
+.Xr ioctl 2 ,
+before the interface will transmit or receive any packets.
+.Sh ROUTING
+The driver places a
+.Tn HOST
+entry in the kernel routing tables for the
+address given in the
+.Dv SIOCSIFDSTADDR
+.Xr ioctl 2 .
+To use the
+.Tn DMV
+as a
+link between local nets, the route to the remote net must be added manually
+with the
+.Xr route 8
+command, or by the use of the routing process
+.Xr routed 8
+on each end of the link.
