Async Professional 3这个工具包包罗万象:你在DELPHI和C Builder下编写通讯程序的一切。从简单的通讯到发送传真、寻呼以及INTERNET应用,只有Async Professional将所有通讯功能集中一起而又价格公道。Async Professional 3建立于TurboPower早期获得大奖的通讯库,并加入了你所需要的功能。一些强大的新功能包括数字寻呼(甚至基于INTERNET),FTP文件传输,RAS拨号自动脚本,新的高级VT100终端,FAX服务器控件以及其它等等。试用版(只有IDE运行时才工作)。-Async Professional 3 of the tool kit all-inclusive: you DELPHI and C Builder prepared with all the communication process. From simple communication to send a fax, paging and INTERNET applications, only Async Professional all communication functions together and at reasonable prices. Async Professional 3 was established in early TurboPower award-winning communications library, and add the features you need. Some powerful new features including digital paging (even based on the INTERNET), FTP file transfer, RAS dial-up automated scripts, the new senior VT100 terminal, FAX server controls, as well as other and so on. Trial version (only run when the work of IDE).
