Solved!<br />

The problem was in my serial port code and it arose from an incomplete understanding of serial port programming.<br />
<br />
In summary I was not trapping serial port events.<br />
<br />
I will paste a sample of working code as soon as I have everything working satisfactorilly - hopefully tomorrow.

Solved!

The problem was in my serial port code and it arose from an incomplete understanding of serial port programming.

In summary I was not trapping serial port events.

<div class="content wysiwyg-content">
I have an enfora GSM 1218 Modem. I am writing an application that reads SMS off the modem. The application also detects phone calls to the modem and logs the calling number. SMS messages come from mobile phones and the internet (SMSC).<br />
<br />
Currently I am using a combination of +CMGL and +CMGR to read the SMS messages. I am using +CLCC to detect ringing and to retrieve the calling number. <br />
<br />
This requires that I continously poll the GSM modem.<br />
<br />
I would like to use the +CMTI notifications to simplify the reading of SMS. I have tried +CNMI=2, 1 but I am not receiving any notifications.<br />
<br />
When I log onto the phone with Hyperterminal +CTMI notifications are shown with this CNMI setting.<br />
<br />
My program goes into a loop that reads the GSM phone com port, but receives nothing.<br />
<br />
What am I doing wrong?

Problem with reading SMS from GSM Modem

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.
