Other applications may require the PIN code to be sent prior to a callback call or 
prior to sending an SMS message (see Technical Note 33 ‘Sending SMS Messages 
using GSM modems’). For those applications which also use Instruction 97, the 
AT+CPIN can either be sent first (as above) followed by a second call of P97 to 
force the callback (once the first call is successful) or the AT+CPIN command can 
be incorporated in the normal dial string. Please contact Campbell Scientific if 
further advice on these techniques is needed. 

If a COM110 with the PIN feature enabled is to be used with a PC as the base 
station, the 

CPIN=nnnnnn

 command can be included at the end of the Modem 

Initialisation string. 

The COM110 will respond with a code indicating an error condition if the 
PIN is sent more than once after it has been powered  up. This will not 
prevent the system dialling correctly.
