I have a GSM Modem (Wavecom Fastrack Supreme 20) that I need to put into use for a new project.
I will connect the modem to a Windows XP computer and the modem needs to be able to receive SMS messages that will contain a two word text message separated with a space, the first word will be a pin code that needs to be verified using a previously uploaded code list in excel, this list will be updated every day, if the code is correct then the phone number of the sender, the pin code, time and date and the second word of the message need to be saved in a excel sheet that needs to be sent by e-mail every 30min (configurable time period). If the code is incorrect, then the modem need to reply to the sender with an error message.
Only one time can each pin code be used, so after validation the code has to be [url removed, login to view] I should also be able to send SMS messages from this modem.
That is it.
