Trouble with HP 59309A Digital Clock

I am trying to get that thing to send the current time to an HP-87
but so far it is refusing to work.

I have succeded in sending commands TO the clock (e.g. OUTPUT 717;"P" stops
the clock while OUTPUT 717;"T" restarts it). After both commands the
"ADDRESSED" LED comes on, but if I do a ENTER 717;A$ the HP-87 freezes.

I do not have the manual, so I am bit lost.

I also have a couple of questions regarding this machine:

a) What does the INT/EXT switch do? My machine appears to work only when the
   switch is in the INT position.
b) Both data and time digits have their decimal points lit. Is this normal?
   Can I turn them off?

Thanks
