Using EHS6 ASC1 UART without RTS/CTS lines connected | Telit Cinterion IoT Developer Community

Hi all, 

I would like to connect an external RS-232 peripheral to the ASC1 UART on the Gemalto Concept board.

Unfortunately, I cannot access the flow control lines on the external hardware I wish to connect to, and the AT command set document (DocID:EHS6_ATC_V02.000) says that the UART must use hardware flow control and the AT\Q commands simply respond OK but doesn't change the flow control settings.

Is there a way of using the ASC1 port via Java, without hardware flow control connected?

Or have I fallen at the first hurdle?
