For Telnet hosts that support the SEND-LOCATION option (and may request during connection), use this value to enable support for SEND-LOCATION.
The value you enter here will be sent to the host during the connect() method and is typically the IP address associated with a web user involved in this connection.
For example, the FVTerm application sets this value based on the IP address of a user that is connecting, in case the host being connected to requests SEND-LOCATION be supported.
