Hi Mike,

There have been significant changes to the networking layer in the upcoming release.
Solving your issue makes the most sense using the latest code base.
Please download the latest sources to work out this issue:

    1 - Download https://github.com/markpizz/simh/zipball/master Saving what that URL returns as a .zip file
    2 - Unpack that zip file with the command: 'unzip -aa zipfilename.zip'
    3 - Build the vax simulator with: 'make vax'

This will build a simulator with networking support and we can work from there to troubleshoot your issue.

Let me know if you still have issues.

Good Luck.
