I have a GSM Modem manufactured by ZTE Corporation. I want to develop an application to send SMS messages via this device. The problem is I can't connect to the COM Port. All what I can see in the Device Manager is the HSPADataCard Diagnostics Interface on COM22 and HSPADataCard NMEA Device on COM24. I have tried to connect using putty on both ports but I failed.
I was wondering if I could use TAPI to send SMS. Any ideas on how to achieve my goal are welcomed.
Also, do you know any library for Delphi ?
