Addr is reset to 0,0 once opened. So, you need to perform these
operations in order: open addr; write ctl; then read addr.

There's a nice way to do this if you can give rc access to the acme
files (try 9pfuse(4) with FUSE).

;9pfuse unix!`{namespace}^/acme mnt
;<mnt/acme/1/addr{
	echo 'addr=dot'>>mnt/1/ctl;
	cat;
}
         93         234 ;

By the way, your question motivated me to give 9pfuse a try. Also,
it lead to my realization that, in rc, you can put the redirections
in front of the command. Hooray!
