EDEVICE CONFIGURATION PROTOCOL
The Edevice Confi guration protocol uses the ONC remote procedure call
(RPC) model. This model allows an application executing on one computer
to conceptually call a function on another computer.
The client identifi es the remote procedure by means of a program ID,
program version, and procedure number. This information is encoded into
an RPC communication packet with the procedure argument values. The
message is then sent to the RPC service running on the server device, where
the target procedure is then executed. The server is required to respond to
all procedure calls with an RPC reply message containing any/all procedure
return values.
Table B.1 lists the RPC messages used by the Edevice confi guration protocol.
Messages that apply to the 8065 are marked by an 'x' in the 8065 column.
B.1 PROTOCOL BEHAVIOR
The client shall issue an RPC command to the Edevice directing the action
to be taken. The Edevice shall attempt to execute the action and will then
reply with an RPC reply.
All confi guration messages pertaining to values or modes shall contain an
Action boolean indicating whether the action is to be a read of the current
setting or a modifi cation of the current setting. Edevice default values are
listed in Section 1 of this manual.
