I tend to disagree.

The original line writes 1 byte into the location $0000, while your line
writes 2 bytes, one to $0000, and one to $0001.

Interestingly, the byte written into $0001 is (most probably, would have
to check to be absolutely sure) a $0D or $00, as your line ends with a
CR. While this does not do any harm, it does not help you in the first
place. You just "mask" an error you have, working around that one.

In fact, I think your problem with the C code most probably is that you
forget to send the CR after the line. (I would have to check again if
this CR is really needed, but this is my guess).
