Thanks Wayne - the JMRI wepage at??says it can be done with a terminal server.? But I get confused what type of terminal server the JMRI narrative is describing. The Dave Zuhn webpage JMRI narrative points you to is no help to me.? The terminal servers I have web browsed are expensive and don't know which type I need.? Yes I would like wireless connectivity from my laptop with the JMRI software downstairs to the NCE controller upstairs.
