I've recently discovered and started playing nethack. I know I can play it locally, but I'm sitting at different computers all the time so I found nethack.alt.org that let's you telnet into their servers to play the ASCII art terminal game. On most computers, the telnet session appears fine and I have no problems. But on my main laptop, some things don't display correctly. I don't telnet into anything else (RDP and VPN meet my usual needs) so my only point of reference is this nethack server.
The biggest visible malformations is when I go to look at the list of running games. The game however looks just fine.
This should be a neatly laid out table (as it is on every computer other than my laptop). As I move up and down the list, the rows tend to be added to the bottom of the window instead of updated in place.
I wish I had other examples outside of this game to say why my telnet is messed up. I don't know where to look. My cmd is at the normal 80x25 dimensions, changing any of the Edit Options doesn't seem to impact this. What else can I do?
