// Description:
// This file initiates the "Data Call dial-up networking call-back" scenario for 
// the GSM Test Harness.  This test is setup to make an outgoing data-call that transfers
// data and then is terminated from the remote end.  The test then quickly responds to 
// an incoming call.  Data is received and the call is terminated again from the remote end.
// The client (application) side must start the emulator and drive the ETel API.  The 
// emulator side runs the designated script.
//
