Newline after receiving "AA" on Windows Application Form

Question

Hello,

 

I am designing a Protocol Data analyzer in c# by using Windows application Form. I am receiving data at speed of 5.25 Mbps from COM Port & i want to show this data over Windows Application.

 

So now i am able to get data over window. However i want to split string to newline & show the time as soon as i get "AA" (AA is my Preamble in protocol Header). 

 

My Protocol data stream is as mentione below:

 

AA 01 00 13 59 A1 02 61 6A A1 02 61 09 00 01 81 00 01 9B D3 32 72 23 AA

 

I have attached my source file. 

 

So how i can do this? Any suggstions?
