I have been working with my UNO for a little while now and making progress.
I am trying via RS232 to read a string of data from my weigh scale and display it through an LCD display connected to my UNO.
I have a TTL converter and null modem adapter connected to my UNO as well as an LCD display.
The Serial Monitor reads the data properly from the scale. I need to display only part of the data stream on my LCD. It sends the data as a string.
While it reads data from the scale, I CAN print various messages to my LCD along with reading the data from the scale at the same time, just not the actual Serial Monitor data.
My Serial Monitor displays:
This is how the scale sends the data:

I have tried a few versions of parsing the data and nothing works yet, I am not sure if I even should be trying to parse the data. It SEEMS like what I should be doing, but it's not working so far.
Here is my code with some notations I added along the way as I tried a few things.
