Redis redis-cli issue with vt220 telnet

I need to connect my company server with VT220 via telnet and redis-cli keeps blacked out as soon as I type the command. It looks like escaping character issue. i.e. even when I type "PING" and hit space key, all outputs afterwards are blacked out.

Is there any thing I can fix this issue? I know ANSI based telnet has no issues at all. but I need to connect with 7-bit VT220. Please help...

As a workaround, you don't have to use redis-cli to talk to redis, you can use raw telnet.

telnet your-server-host 6379 And then you can type (some) commands.

ps: I just added a toy redis_cli subcommand to my ws project, if you want to give it a try. It is very alpha ... (it will not handle all commands) -> https://github.com/machinezone/IXWebSocket

Thanks for the answer. I know I can use Windows CMD via telnet without issues. but my point is to use vt220 as legacy mode.
