Re: [lwip-users] Network Virtual Terminal

Thanks Robert.

Part of my problem was that I was echoing all the NVT commands back 
which can cause confusion when
you reverse a setting later.  I am sort of hoping for a simple option 
that turns local echo on the PC.
It appears that I may have to follow your linemode  approach to get 
consistant behaviour will all clients.
