用MODEM来发短信，包括PDU的算法，较为详细！-Sends the short message with MODEM, includes PDU the algorithm, is more detailed!

iWebSMS2000是一个基于Web的短信平台 =============================================================================== 目前政府、企业信息化，对消息的获取提出了更加严格的要求，需要随时随地、不受 空间、时间、地点的限制；要求主动获取消息，要求能在节省成本，同时保证信息安全， 在这种情况下，本公司自行研制开发了基于Web方式的iWebSMS2000短信消息平台管理方案。 这个方案是采用金格无线Modem作为短信收发设备，并在此基础上开发了金格短信服务器软 件和Web应用组件，支持JavaBean或COM调用方式，提供高可靠的扩展性，方便了政府、企 业和软件开发商应用集成。-iWebSMS2000 is a Web-based messaging platform =========== ======================================== =========================== government, corporate information, Access to information made more stringent requirements, the need anywhere from space, time and location constraints; Active demand access to information requests in cost savings, while ensuring the security of information, in this case, The company developed its own Web-based information to the SMS platform iWebSMS2000 management programs. The program is the use of lattice as a wireless modem SMS transceiver equipment, and on this basis the development of the lattice messaging server
