Parent is most likely referring to the telnet GOAHEAD character and its related SUPPRESS GOAHEAD protocol: https://tools.ietf.org/html/rfc858 https://tools.ietf.org/html/rfc858 I am the author of a MUD client for iOS[0] that, like most other clients, will capture and silently discard the GOAHEAD character.
