Nothing prevents the PDP8 from sending data even if your serial device 
is turned off. :-)

Hmm. The paper tape of the ASR33... Was there some signal run in 
parallel for the reader run? What did you hook the other end to then? 
The KL8-JA (and KL8-E) don't have any more signals that I can remember 
offhand. There was an option for the KL8-JA (called KL8-M I think) which 
implemented partial modem signaling, if you needed that. Never seen one 
in real life, and I can't remember if I ever read any documentation of it.
But you'd most likely need software to actually implement the signaling 
anyway. It won't be a hardware-only solution...
