 I just went back to the "decnet8.doc" file which is a DECnet for RTS-8
 user manual and internals document.  Among other things, it describes the
 protocol (DDCMP and NSP).
 
 I don't know much about PDP-8 software, but if someone manages to get that
 code running I'll take a stab at PyDECnet support for talking to it. 
 
  Can pyDECnet do asynchronous DECnet over a telnet port?  I'm thinking the
 easiest way to set this up for debugging/testing would be to use simh for
 the PDP-8 and a virtual KL8-E connected to pyDECnet. 
Yes, it's documented in doc/config.  Your choice of DDCMP over TCP (straight 8-bit
data) or TCP over Telnet (8 bit data with handling of  escaping for the Telnet command
character 0xff).
   Ultimately it would be nice to run it on real
hardware with a real async
 DDCMP connection, but that's for later. 
PyDECnet can do that as well.  It's how I talk to my Pro (since I don't yet have a
CNA driver).
