If you want to communicate from PyDECnet to a Phase III node, a new bugfix release V1.1.1
(on akdesign.dyndns.org:8080 <http://akdesign.dyndns.org:8080/>) may be helpful. It
fixes an NSP bug that was setting a Phase IV only flag, and some Phase III nodes
(DECnet/RT for example) then toss the offending message.
