5.1.2.2. Transfer 
Settings 
The Transfer Settings allow different 
modes. They are selected by the basic 
“Mode” setting. Depending on the 
current mode, only some of the many 
parameters are useful. The web configuration hides those parameters 
without function.

Basically the NetCom Devices can act as a server or as a client. As the 
main difference a server waits for clients to contact it, while a client 
actively contacts a server. A NetCom can do both, and partially both at 
the same time. Keep this in mind throughout this section. 
5.1.2.2.1. Driver 
Mode 
Only very few parameters have a 
function in “Driver Mode”. NetCom is 
operating as a Server. It accepts two 
connections per serial port. One 
connection is used to transmit the 
serial data, this is the 
“TCP Port(Data)”. And the other is 
used to transmit control information, “TCP Port(Control)”. This control 
connection includes the configuration of the serial port, as well as 
signals for changed Modem Status lines. This mode is required when 
the serial port is operated via the Virtual Com Driver, it is default.

The NetCom can check if the connected Client is still alive. This may 
be done, when a second Client wants to establish a connection 
(
On Connect
). It may also be done in regular intervals (
Polling
). 
 
5.1.2.2.2. 
TCP Raw Server 
As TCP Raw Server NetCom operates 
very simple. It only waits for incoming 
data connections in Raw IP mode. As 
with the Driver Mode only the data 
connection is defined. As a special 
configuration NetCom allows for more 
than one connection at a time. If the 
number is raised, it is the responsibility 
of the customer to ensure correct 
operation. Firmware version 2.2 added
