You've hopefully already done this, but go in to the emulator and check what it's set to, and do a TERM in UV to make sure that's the same. I don't think the issue is actually ssh. On a windows universe server, just opening up a cmd.exe window and running the above commands duplicates the problem. That makes it sound like that is the problem. I don't know what emulation cmd does, but I've had that problem. What I'd do is simple. Set TERM to a type you know works elsewhere. Set your emulator to raw so it displays all the characters it receives. And then write a basic program to spit out various @(-x) sequences so you can check what's actually being sent. Because it sounds like either (a) you've got a mismatch between the emulation on UV and your terminal prog, or (b) (nasty), ssh is stripping escape sequences as it passes stuff through.

Re: [U2] UV Windows SSH without telnet service
The most recent issue of Spectrum magazine detailed a process which I will summarize here: 1. Use PuTTY to establish an SSH session from Windows client to Windows server. 2. In Putty, open a local port forward, so that a particular socket on the client is forwarded to the server. 3. Run your favorite telnet client, in telnet mode, to connect to localhost and the socket (port) referenced in item 2 above. The telnet client connects to the local port, which forwards it (within the secure SSH connection) to the server. The SSH daemon on the server forwards the connection to the telnet port (usually 23) on the server, wher UV receives it. As far as UV is concerned, it is running telnet. However, all external traffic is authenticated and encrypted.

Re: [U2] UV Windows SSH without telnet service
AccuTerm is SSH enabled. You can use it to connect to the WinSSHD server then forward that, via telnet, to the UV server.
