<span style="font-family:Verdana,sans-serif; font-size:9pt Dear Experts.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt I want to write a Solution with VB.Net for
Receive "Users" requests and Send specified information to
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt them with SMS.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt I use D-Link GSM-Modem (Model
WM-156).
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt This model/type of GSM-Modem, has
embeded Driver and a Application for Sending/Receiving SMS
on it, and also we can attach MicroSD to the Device.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt 1-Send/Receive with GSM-Modem and D-Links application :
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt <span style="font-family:Verdana,sans-serif; font-size:9pt <img alt="" height="214" src="http://social.msdn.microsoft.com/Forums/getfile/64319" width="395
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt when i attach GSM-Modem to USB port, D-Link app , run automatically , then I heared noises on my Speaker, like when turn on a Mobile. I think this Signals "Hand Shake" with My GSM-Network.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt and then i can send/receive/manage my SMSs on my
SIM .

<span style="font-family:Verdana,sans-serif; font-size:9pt Dear Experts.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt I want to write a Solution with VB.Net for
Receive "Users" requests and Send specified information to
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt them with SMS.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt I use D-Link GSM-Modem (Model
WM-156). <p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt This model/type of GSM-Modem, has
embeded Driver and a Application for Sending/Receiving SMS
on it, and also we can attach MicroSD to the Device.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt 1-Send/Receive with GSM-Modem and D-Links application :
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt

<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt when i attach GSM-Modem to USB port, D-Link app , run automatically , then I heared noises on my Speaker, like when turn on a Mobile. I think this Signals "Hand Shake" with My GSM-Network.
<p style="text-align:left; line-height:normal; unicode-bidi:embed; direction:ltr; margin-bottom:12pt
<span style="font-family:Verdana,sans-serif; font-size:9pt and then i can send/receive/manage my SMSs on my
SIM .
