What is this ? and where are the checksums Newby in all this so forgive me
Understand that the characters you're seeing are only representations of the binary data actually being received. If your baud rate is correct. If your baudrate is wrong however, you're just getting representations of junk bits.

It looks like binary to me, too. Note the character representations of some of the control characters. On the bottom line is NUL NUL NUL just before the ASCII 'F'. That is binary data 00h 00h 00h 46h displayed as ASCII characters. The good news is that RealTerm appears to be able to display hex, binary etc so search around for that in the terminal menus.
From the RealTerm description:
Binary display modes -Hex,Int,Float,Signed/Unsigned,
https://sourceforge.net/projects/realterm/

There's likely more than that going on but starting with a hex output would be good.
Good luck and welcome to AAC!
