// Open it (if not)

And then switch to data mode ( adl_fcmSwitchV24State (myUartHandle, ADL_FCM_V24_STATE_DATA); ) to start communication.
All work fine !
But since I upgrade the firmware from R74 to R74a the device does NOT answer ! If I downgrade to R74 all re work fine.
NOTE: The connected device works ONLY if CTS signal is kept high all the time. But according to the doc “When <DTE_by_DCE> parameter is set to 0 (none), the CTS is kept high all the time”.
We encountered the same issue and already reported it. It is confirmed by wavecom and should be corrected in Oasis 2.33, the release after the upcomming one.
