[Simh] FW: FTP client connecting to SIMH/OpenVMS?

Read the SIMH FAQ - there is a section dealing with 'cannot communicate
between host PC and VAX'.

It can be solved by bridging a pseudo-adapter to the main ethernet
adapter or using a second nic.

I believe this is a known problem with SIMH (actually I believe it's a
problem in the underlying networking library used by SIMH).  To
communicate between the host PC and the emulated VAX, the host PC needs
to have an ethernet NIC which is dedicated to the VAX.
