[has VPN to the company and a shell on a remote server, via private IP 
outside the LAN's subnet, open]
[types "Foo", sans <ENTER>, into the shell]
[turns off VPN]
[types "Bar" <ENTER> <Tilda> <Dot> into the shell]
[no trace of the server echoing any of that back, but the client 
immediately terminates and returns me to the local shell as I hit <Dot> 
- all as expected and oft-used]

... I'm afraid that you'll have to state the exact version of OpenSSH 
involved on both sides when you see a different behavior ...
