I am forwarding a conversation I had yesterday about a DECnet implementation for Unix, Linux, and Windows, which originated with James Corrigan's announcement on the linux-decnet mailing list (close to the bottom of this post). It seems rather timely given the recent conversations here about transferring files, and Johnny Billquist's comments about bugs in linux-decnet. I will invite Mr. Corrigan to join the SIMH mailing list.

These drivers are well implemented everywhere now allowing the change of address to the AA-Xx-Xx DECnet address space. Bao also greatly improved the performance of our LAT
