chunks

I need to understand chunked messages better. Here's a typical 'get track title' command:

>> 09 00 60 b0 e8 00 00 09 00 01
TX|.. ..  ` .. .. .. .. .. .. ..
 < 19 00 12 b8 e8 00 01 09 00 01 41 42 43 00 00 00 00 00 00 00 00 00 00 00 00 00
TX|.. .. .. .. .. .. .. .. .. ..  A  B  C .. .. .. .. .. .. .. .. .. .. .. .. ..

Here's one with a two-chunk title (I just put loads of spaces in there):

>> 09 00 60 b0 e8 00 00 09 00 01
TX|.. ..  ` .. .. .. .. .. .. ..
 < 19 00 12 b8 e8 00 01 09 00 01 41 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20
TX|.. .. .. .. .. .. .. .. .. ..  A

>> 09 00 60 b0 e8 00 00 09 00 02
TX|.. ..  ` .. .. .. .. .. .. ..
 < 19 00 12 b8 e8 00 01 09 00 02 20 20 20 20 20 20 20 20 42 43 00 00 00 00 00 00
TX|.. .. .. .. .. .. .. .. .. ..                          B  C .. .. .. .. .. ..

I think it's maybe a case of just terminating on a sufficient number of zeroes.

How does this affect sending?

(todo).
