Reading a serial stirng and breaking it apart based on hex delimita

I caint see how to do that.

At the bottom of the dialog for setting up the serial connection it says:
Tip: the "Split on" character is used to split the input into separate messages. Can accept chars ($), escape codes (\n), or hex codes (0x03).
That is also included in the help text.
So you should be able to use 0xfe. Try that first and it should give you alternately an empty payload then a buffer. If that works try 0xfefe, but I don't know if that works. You will soon find out.
