2 Greeting Protocol

When a Lisp process first establishes a connection to the server, it sends a 16 bit quantity which represents "1" to it. The server using this to decide whether to byte swap words when sending them to Lisp. The general policy is that all data is presented to the Lisp process in the order that Lisp uses.

Following the byte swapping information, the Lisp process sends an initial message which contains:

• A string giving the target X display name
• A string for the application name
• A string for the application class
