20.5 Inventory taking per UDP/8513
Larger installations often require that an inventory be taken of
all the Com-Servers currently in the network. This can be done
using UDP Port 8513. After receiving a network packet directed
to this port, the Com-Server replies to the respective sender
with an info packet. This contains the network-relevant basic
parameters as well as information such as the current
connection status.
Whether a packet was received by a Com-Server per broadcast
or directly addressed to it makes no difference in generating
the info structure. The only factor is that UDP-Port No. 8513 is
used.

For reasons of downward compatibility, the Com-Servers
continue to support the previous UDP infoport 8512. In
new applications however you should use only Port 8513 as
described here.
20.5.1 The infopacket
Each infopacket consists of 3-6 data structures.
BOX_VERSION
contains information on the respective model of the Com-Ser-
ver and its firmware status. The structure
BOX_DESCRIPT
provides the network-relevant data such as MAC- and IP-
address. The 3.-6. structure
PORT_DESCRIPT
provides
information about the configured mode and the current
connection status of the individual ports. The total length of
the InfoPacket is calculated as follows: 1
0 + 22 + (port_no x
10) bytes.
