Hi folks,

We have a Q64 modem with the following response:

AT+WIOM=2  
+WIOM: “GPIO0”,4  
+WIOM: “GPIO1”,4  
+WIOM: “GPIO2”,4  
+WIOM: “GPIO3”,4  
+WIOM: “GPIO4”,4  
+WIOM: “GPIO5”,4  
+WIOM: “GPIO6”,4  
+WIOM: “GPIO7”,4  
+WIOM: “GPIO8”,4  
+WIOM: “GPIO9”,4  
+WIOM: “GPIO10”,4

OK

and another Q64 with the following response:

AT+WIOM=2  
+WIOM: “GPIO0”,4  
+WIOM: “GPIO1”,4  
+WIOM: “GPIO2”,4  
+WIOM: “GPIO3”,4  
+WIOM: “GPIO14”,4  
+WIOM: “GPIO15”,4  
+WIOM: “GPIO16”,4  
+WIOM: “GPIO17”,4  
+WIOM: “GPIO19”,4  
+WIOM: “GPIO20”,4  
+WIOM: “GPIO21”,4  
+WIOM: “GPIO22”,4  
+WIOM: “GPIO23”,4  
+WIOM: “GPIO24”,4  
+WIOM: “GPIO25”,4  
+WIOM: “GPIO26”,4  
+WIOM: “GPIO27”,4  
+WIOM: “GPIO28”,4  
+WIOM: “GPIO29”,4  
+WIOM: “GPIO30”,3  
+WIOM: “GPIO31”,4  
+WIOM: “GPIO32”,4  
+WIOM: “GPIO33”,4  
+WIOM: “GPIO34”,4  
+WIOM: “GPIO35”,4  
+WIOM: “GPIO44”,4  
+WIOM: “GPIO45”,4  
+WIOM: “GPIO46”,4  
+WIOM: “GPIO47”,4  
+WIOM: “GPIO48”,4

OK

Both modems have a firmware version R74.000 and our application uses the GPIO30 to generate a signal to a microcontroller.

Does anybody know how must be configured the first modem to use the GPIO30?

Thanks for your reply.
