SMSC Relay VCL SDK

SMSC Relay VCL SDK library is a set of optimized VCL components enabling quick creation of applications implementing the communication with the SMSC through TCP/IP protocol. What's new in version 2.1? - SMPP protocol now allows to bind as transceiver, transmiter and receiver. - Executable demo applications are now capable of sending UNICODE messages in Windows NT/2000/XP. - New licencing policy allowing to buy components for selected protocols. - Changes in setup program for clean installation of components and examples for selected protocols. - Added UCP protocol authorization based on OT-60 operation. - Added ability to set an alphanumeric signature (originator) in UCP protocol (all protocols are now fully alphanumeric originator enabled). - Added UCP protocol KeepAliveOperation property. - SMPP protocol now allows to set message delivery time and validity The library consists of four components, each of them implements one communication protocol. Supported protocols are SEMA (version 8.1), CIMD2 (version 1.2), UCP (version 2) and SMPP (version 3.4). Key features: - Multithreading construction ensures maximum efficiency of the sending and receiving messages process - Receiving messages sent by users to special (short) numbers (contests, surveys, voting services etc.) - Possibility to send and receive SMS and EMS messages, messages containing images, animations, logos, sounds etc. - Possibility to send and receive seven-bit text messages, eight-bit messages with binary data as well as text messages encoded in Unicode (UCS2) standard - Full information about the message delivery status - Support for messages containing user header (UDH) and for encrypted messages - Possibility to send messages in Direct Display mode (FlashSMS) - Possibility to attach an alphanumeric signature to messages - Network connection keep-alive functionality - Tested in cooperation with many SMSC configuration
