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.

$HOST:$PORT<CR><LF>

 

For a SOCKS compliant proxy server, enter the USERID for SOCKS authentication.
