Pnlite - using SSL

I want to connect to a Citrix Secure Gateway using SSL from a wyse V10Le client running WTOS 7.0_113.

What is the correct syntax for connection?

I have found a sample wtos ini file but I have not been able to figure out how to tell the client to use SSL. Do I have to specify the location of the SSL certificate?

#Citrix server.
PnliteServer=www.mysecuregateway.com

Thanks
