Exactly this code sniplet was located directly after the call to
load_serial_bin() in cmd_boot.c:do_load_serial_bin() before I started
looking for the problems. When I sent my first patch which _removed_
this code I somehow forgot to send you the hunk which adds it at the
right place. So this patch does not add new code, it only re-adds the
hunk which was removed instead of re-located to the right place.

Before: 
	load_serial_bin();
		download via kermit
		say "I'm finished"
	throw away garbage characters
	go on

Now: 
	load_serial_bin();
		download via kermit
		throw away garbage characters
		say "I'm finished"
	go on. 

I hope you understand what I mean...
