Dear Maintainer,
Opening a telnet link in gopher that tries to connect to a server that cannot be reached.
Pressing Ctrl+C exits telnet and shows the prompt to return to the gopherhole.
Press <RETURN> to continue shows up. After pressing return, it returns and beeps in an endless loop. No more control is possible.
To check
gopher port70.de
Select "[43] Plain text world map <TEL>"
Trying 0.0.0.23... appears, then press Ctrl+C and enter.
That telnet target is unreachable, but that should not result in a freeze of gopher after returning.
