The -x option is required when the MobiLink server is not on the same device as the QAnywhere UltraLite Agent.
You can specify -x multiple times. This allows you to set up failover to multiple MobiLink servers. When you set up failover,
the QAnywhere UltraLite Agent attempts to connect to the MobiLink servers in the order in which you enter them on the command
The QAnywhere UltraLite Agent also has a Listener that receives notifications from the MobiLink server that messages are available
at the server for transmission to the client. This Listener only uses the first MobiLink server that is specified, and does
not fail over to others.
