| Telnet | Check this box if your proxy server uses the Telnet proxy server protocol. |
| HTTP | Check this box if your proxy server uses the HTTP proxy server protocol. After connecting to the proxy server the following data is sent: CONNECT host::port HTTP/1.1 Host host::port Proxy-Authorization: Basic username:password |
| Proxy Name/IP | Enter the domain name or IP address of the proxy server. |
| Proxy Port | Enter the proxy server port number. |
| Username | (Optional) Enter the user name required by the proxy server. This field is only valid for the HTTP proxy server protocol. |

| Connect Command | (Optional) This field is used differently for non-SOCKS compliant and SOCKS compliant proxy servers. |
For non-SOCKS compliant proxy servers, enter the connection command required by the proxy server. You can use the following variables in your connect command:
| $HOST | Replaced with the Host Name from the Host Pane. |
| $PORT | Replaced with the Port Number from the Host Pane. |

| $HOST:$PORT<CR><LF> |
For a SOCKS compliant proxy server, enter the USERID for SOCKS authentication.
