Packet types (byte TYPE)
The following three packet types are used for sending
configuration data:
• TYPE = 1: Writing parameters in the Com-Server
This packet is sent by the SLIP computer to the Com-Server.
The Com-Server carries out the configuration and deletes
the packet. A packet for configuring the IP address and
subnet mask would look as follows:
0
TYPE
1
1
LEN
10
3
IP address
hex: AC 10 EF 1
(172.16.231.1)

• TYPE = 2: Request for reading parameters
This packet is sent by the SLIP computer to the Com-Server.
The Com-Server sends a response type (TYPE=3) with the
contents of the requested parameters. The packet contains
the fields TYPE and LEN and a list of the desired parameter
numbers (PARAM_NO). A packet for reading the MTU and
the MAC address would look as follows:
0
TYPE

• TYPE = 3: Response to a request for reading
parameters
The Com-Server uses this packet to reply to a request for
reading parameters (TYPE=2). It is used for sending the
requested parameter contents. This packet is constructed
like TRYPE 1. The reply to a request for parameters MTU and
MAC address would look as follows:
0
