The data transfered via Diagnostic port to my laptop when rebooting PM783F was unreadable
For Handshake, you can use the setting None or Hardware (RTS/CTS). Just make sure that if you use Hardware Handshake the lines in the cable are connected to the plug on both sides and the Levels are actually set by the Terminal.
Please note, that even when the baud rate is set to 19200 the Hardware-Test messages will still come with 9600. You have to wait until the tests are over to see the diagnostic messages ungarbled.
Please find attached a demo project for a stone crusher. It is available for AC 700F or using the Softcontroller (Controller Emulator) instead.
It is available in English or Chinese (because the intern who did it is a Chinese national) Documentation is also included.
Hope that helps
