I have a GSM modem manufactured by ZTE Corporation. I want to develop an application for sending SMS messages through this device. The problem is that I cannot connect to the COM port. All that I see in the Device Manager is the HSPADataCard diagnostic interface on COM22 and the HSPADataCard NMEA Device on COM24. I tried to connect using putty on both ports, but I failed.
I was wondering if I can use TAPI to send SMS. Any ideas on how to achieve my goal are welcome.
Also, do you know any library for Delphi?
