Setting Auto TCP operating mode parameters
In Auto TCP, the SDS acts both as a client and as a server. As a
client, it connects to the server at the specified TCP address and port.
As a server, it will accept a Raw TCP mode connection.
Note: Auto TCP is the only
communication mode that lets
an SDS initiate the connection.
communication mode that lets
an SDS initiate the connection.
You can configure an SDS port to use either DSR or Data to initiate a
connection. As with Raw TCP, you must configure all the connection
information (baud rate, data bits, and so forth) on the Serial Port
Setup page. There is no way for the application to tell the SDS what

Auto TCP is also somewhat similar to Raw TCP in that only data
passes through an SDS serial port – there are no headers and no
packet. For this reason, you cannot use Auto TCP with our virtual

You can connect to the SDS via another host and use a port just as
you would in Raw TCP. The main differences between Raw and Auto
TCP are that Auto TCP operates in two modes (DSR and Data) and
