Hi, I have this Fastrack M1306B GSM Modem, to which I connected to my PC using a serial cable.
I use Windows HyperTerminal to check to see that my PC is able to communicate with the modem, and the responses are below.
[b]AT+CRGREG[enter - this i got from one of the posts here not really sure what this is for]
Could some explain what the CREG & CGREG are meant to do, and are these the causes of me unable to send an SMS?
Also please not the LED on the GSM Modem does not blink at all, to which the User Guide stated that it should to indicate network registration & activity.
I use ActiveExperts Messaging Server v4.1 as my application to send an SMS but I would like to make sure that my modem and SIM are working.
Please note I am very new to GSM Modem & AT Commands.
