// The basic idea behind this test structure is that one end will run

// in "slave" mode and the other in "master" mode.  Typically, the slave

// will run on a target platform with the master running on a host.

//

// The slave starts up by listening for a connection on the "SLAVE_PORT".

// In order for the testing to require the minimum stack support, this

// connection (and the protocol) will use UDP.

//

// The master will connect to the slave and send it a request over this

// connection.  Once the slave accepts the request, then master and slave

// will execute the operation, typically a test.  The control connection

// will remain active until the master sends a 'disconnect' request.  The

// control connection will be broken after the reply to this request has

// been sent.
