I had no idea that Konsole could do this until yesterday!  It is very cool. 
It's
great to see software packages which are still updated for modern requirements,
still not forgetting older protocols and practices.

I know how to do this by other means, so I think I'll just take it that telnet
as-is, when used with a TCP connection doesn't handle it.
