.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.
