# Configure World → Connection → Telnet #

The **Telnet** page of the Connection World Configuration can be used to alter the telnet negotiation performed when connected to a MU\*, or to disable it entirely, if the MU\* does not perform telnet negotiation.

  * **Attempt Telnet Negotiation?**: Controls whether telnet negotiation is attempted. Highly recommended for any games which support it.
  * **Starting Encoding**: The encoding to use for the connection. The default is iso8859-1 - this is probably correct for most games, though some may use ascii or unicode/utf-8, and games in other languages may use something else.
  * **Negotiate Encoding?**: If the MU\* supports negotiating encoding via telnet, should we do so? Generally a good idea to leave this enabled, although not many MU\* servers support this (MUX being a notable exception). (Telnet protocol 42)
  * **Negotiate SSL?**: Not currently supported.
  * **Negotiate NAWS?**: Should Potato tell the MU\* the window size? Some games alter their output to make best use of the available screenwidth. (Telnet protocol 31)
  * **Use NOP Keepalive?**: Should Potato regularly send a Telnet NOP to the MU\* to act as a Keepalive? Useful for routers that kill connections with no regular activity.
  * **Handle GA/EOR Prompts?**: Should Potato use the telnet GOAHEAD/EOR characters for displaying MUD-style Prompts?
  * **Persist Prompts?**: When enabled, prompts will remain until cleared, either by the MU\* or by the user. When disabled, the prompt is removed/reset as soon as a new line of text is received.
  * **Ignore NL after Prompts?**: If displaying prompts, should a newline immediately after the prompt GOAHEAD be ignored? Use this if you get a blank line in the output window every time your prompt is changed.
  * **Send Client Info?** Should Potato identify itself? (Telnet protocol 24)
  * **Send Client Name As:** If Potato has been told to identify itself as, how should it do so? Defaults to "Potato".
