you assume the pink only sends 1 byte after you send it the command !NB0R00
but the pink transmits all bytes from var00 up to a stored binary 0 (the CLS character).
So if var00 holds "dog",0 then 4 bytes are returned to the sx.
Actually, when no CLS is stored in var00, pink continues to send bytes from the
next variable and so on, until it encounters a binary 0.

You send a CLS character after you received two bytes. I assume the CLS character
terminates the read command but I am not sure about that.
