I am sending a SMS from one emulator to another. Emulator 1 uses the port address of emulator 2 to send to. If I use the correct port address the message shows up on the 2nd emulator. If I use a false address although the message does not show up the Activity.RESULT_OK shows -1 which indicates that the message was succesfully sent. Can anyone confirm that testing between emulators should produce the error result where appropriate? If so any suggestions as to where to look for the cause of the problem. Thanks Ron
