There is no end of block character, so I assume that just using carriage return and line feed (like any text file) will transmit as a new word. It should not be necessary to take any special pains to do that.
If you were to transmit
X1. Y1.
the 'bandit enter' will automatically be inserted for you, because the 'bandit enter' was used to denote a series of commands combined as a multiaxis move or as a drill cycle or as a mill cycle.
Bandit does not use some G codes in the normal sense. No G01 and no G00 are used, but there are special commands for cutting complete 360° circles that will use /G2 and /G3, otherwise, the code is very abbreviated. I just pass that along in case you get errors right away when you transmit a file to it.
First you get good, then you get fast. Then grouchiness sets in.
