Good day,
I have used the CR1000 datalogger for a long time to acquire data and send SMS using an external modem.Today I installed a CR310-CELL200 and I want to do the same thing as before.I want to use the built-in modem of the cr310-CELL200 to send my sms and I want to know which port to use in the instruction: SerialOpen (SMSPORT, 9600,0,10000,100).
Thank you in advance.
