Very tempting
The 'bundle' says it's a 4-channel, but it looks like they mux them into two ADCs.  's got four BNC probe connectors...    S.   Edited to add: And they admit...

Ring Buffer vs Array Buffer
So set the 'command rec'd' flag on the first S, and ignore the rest.  Won't work if the 'S' is in italic, though...    S.   Edited to add: Unless it's only...

Very tempting
I don't really need another 'scope, the ones I have work very well, but I can get itchy about buying a new one now and then.   No thanks to you, avrcandies, for the link to...

Ring Buffer vs Array Buffer
As an aside, just how long and complicated are these ASCII queries for 'a couple of sensors'?  Are you trying to parse them like a 70's text adventure, "Please tell me the...

Ring Buffer vs Array Buffer
I'd use a straight buffer, but that's mostly because ring buffers are a bit less fun in assembler.  I like your "set flag at EOL, says command has arrived in full, then read'...

Accurate 8-bit timer using 16MHz crystal
I get about 0.12 seconds of plausible error out of a 100ppm 16MHz XTAL over 20 minutes.  That would be easily detectable by eye.   Suggestion for the OP:  Put it in...

I once did a lot of work on a CNC woodcutting machine (a big puppy - it would handle 4x8 sheets easily) that had four motor drive power supplies built with things like that....
