I suspect the person just wanted to set off the serial number from the
rest of the info to make it more distinct.

What he didn't realize is that sending the additional characters only
adds to the possibility of error.  If the space character gets corrupted
due to noise or whatever, the message would be less readable, not more.
The best he could hope for is to break even.

Sending additional characters for purposes of redundancy often helps,
but redundant spaces doesn't really add much.
