Serial Tunnel configuration between EDS - EDS

How do I set up a serial tunnel in between two EDS devices?
The below procedure is for creating a serial tunnel in between two EDS devices with step-by-step configuration changes that are required. We will use Setup mode on EDS as an example.
By default an EDS listens on port 10001 for serial port 1 and, if it has two ports, 10002 for serial port 2. These ports numbers are configurable. Port 10001 is used in the below example.
To have a reliable serial tunnel we need to assign both units a static (fixed) IP-address. Both IP-addresses should be part of the same network or Two different networks that have already been routed and communicable.
In the below example we will assign the following IP-addresses that are from the same network.
EDS1 : 10.4.53.48
EDS2 : 10.4.53.49
+------+ +-----+ +-----+ +------+
|Serial| | EDS | Ethernet | EDS | |Serial|
|Device|--------| #1 |===============| #2 |-------|Device|
+------+ +-----+ +-----+ +------+
10.4.53.48 10.4.53.49The commands necessary for this configuration to automatically establish this connection are as follows.
You will also need to ensure that the port parameters such as baud rate, Parity, Stop Bits, flow control etc. are correct for the serial devices.
EDS#1
Assign an IP address to the first EDS:
Please refer to the User guide as to how to do it step by step.
Leave the first EDS configured to accept the incoming network connections.
Serial settings to be configured on the device.
EDS#2
Assign an IP address to the second EDS:
As mentioned above please refer to the User guide for a step by step procedure.
Configure the second EDS to open a connection to the port 10001 on the first EDS:
Serial settings to be configured on the device.
