How does on go about accessing the Ethernet port with the Arduino on the alpha?
this is a Arduino Leonardo eth right?

LP Alpha's Arduino section is an Arduino Leonardo (using ATmega32u4.)
The latter, by itself, does not have any Ethernet interface capability.

There are ad-hoc Ethernet co-processor HAT (W5100 or ENC28J60 based) to assist (less powerful) Arduino.
On the other hand, most x86 based processor boards will have an Ethernet (or WiFi) interface, It's such an easy task for x86.

So it is a soul searching time to think the reason why and consider the balancing act (or alternative solution.)
May be sending the data Arduino had collected to x86 via serial port is better solution, perhaps? May be Firmata or something else...

I was thinking about collecting it from the serial com already established between the processor and the Arduino. I to use windows(or linux cause I don't want windows crashing) to accept the data and upload it. I just don't know of any text software that is able to grab serial data.

On x86 side (Windows or Linux): Python.

On Windows I have used Cpp, C# and VisualBasic for communication over serial port.

For just testing I am using Docklight-Terminal, but any other terminal software will also do.

Some time ago I saw a VBA macro for Excel that fetched data from measuring instruments via the serial interface and displayed it directly in Excel.
Should also work in Word.
