Well, after much prodding and plodding through manuals, examining my
cable, and some trial and error, I managed to get my printer working
to my (almost) satisfaction. The xon/xoff flow control seems to function
properly now, so now my amiga waits patiently for my printer. I was, 
however, wondering why, since they put all sorts of Data Set Ready
polling into the serial driver, they didn't allow one to select
DSR flow control for external hardware. I've always found xon/xoff
sooo inelegant...
	Also, I have been playing with a program which opens a screen and
no windows. When I wanted to add a close gadget to the screen, I did
everything I was told to in the manuals. I set up the gadget's Gadget
structure, and put a pointer to it in my NewScreen structure, and I
am all set, right? Wrong. Now I have to figure out how to get messages
from this gadget. I don't want to open a window to do so, and even if
I did, my manuals still don't say anything more about screen gadgets!
This may be covered in the 1.1 Rom Kernel manual or the erratas for the
others, but I doubt it. What I'd like to know, is how do I set up a port
for messages from Intuition about my gadget and have Intuition send
the appropriate messages to that port so that I can tell when the user
has hit the mouse button within a 10 by 10 square so that I can 
reclaim the memory used by the screen! (Boy, all this fuss for just that
Martha?) Any help would be greatly appreciated. I think this is the right
approach to the problem, where opening up a 10 by 10 borderless backdrop
window on top of the screen's title bar just to find out when to exit
is a touch inelegant, and is merely unnecessary code.
