Use this utility to use an MI vector to supply a GSM modem PIN code. When you use this function, the controller will look for the number in the MIs, bypassing the PIN code in the SMS message dialog box.
Note that since there is no Ladder element for this function; you perform it by:
Storing the start address of the MI vector needed to contain the PIN into SI 141,
Storing 410 into SI 140 to select the function. Storing the function number calls the function. In your application, call the function after you have entered all of the other parameters. Note that when you run Test (Debug) Mode, the current value in SI 140 will not be displayed.
The PIN code should be called before the modem is initialized; the function should therefore be called as a power-up task.
Note that if the MIs contain an incorrect PIN code format, the error will be indicated by Error message #18 in SI 180--Illegal PIN Format.
