I am using GL865 with 2 DTEs connected on ASC0 and ASC1, and AT#SII=1. The DTEs are 2 MCU and they can’t run Telit serial port MUX tool. Both shall be called by a remote modem through CSD. When I remotely enter the ATD<..> command I see the first RING on both ports but only ASC0 goes on ringing and finally gives CONNECT. My question is, can I use CSD also on ASC1? in other words, there’s a way to switch between the two ports, to decide which one can "answer" the call?
Check ATS0 on both instances set it to 0 to disable auto-answwer at your will.
