Reading Data from Multiple Sensors and Writing Data using LabView

[nah16d]

Hi
I am trying to receive some sensor data and transmit it to the ground station using an antenna. In the groundstation Labview will receive it using a COM port and display the data 
But I am not being able to read or write the data
Can you check my sketch and suggest where I am going wrong?

Why aren't you able to read/write the data?

Which error(s) do you get?

Why don't you cleanup the block diagram?

Are you reading the correct number of bytes for each COM port?

Do you know the basics of serial communication? (Did you set the correct TermChar?)

What is a "sketch"?

In LabVIEW you have VIs with a frontpanel and a block diagram…
