              ZIPCOM Single-Port X.25 Synchronous PCI Card is truly a perfect solution for complex and 
                versatile high-performance synchronous communication applications for X.25 protocol. You simply 
                need to make use of ZIPCOM's Alex API functions to develop your own applications to meet your 
                business requires. 
                An onboard CPU, combined with memory, effectively reduces the burden of the server CPU, 
                bringing overall performance up to 64Kbps on port. 
                The Alex library provides complete HDLC/SDLC/LAP-B X.25 layer 2 data communications 
                control conforming to CCITT, ITU, including frame formatting, bit stuffing, and error detection. The 
                library also provides complete X.25 protocol layer 3 communications control conforming to CCITT, 
                ITU, including package formatting, control, configuration and on-line trace ; and provides the demo 
                source code for programmer to implement his/her applications to the business needs. The 
                programmers easily implement their application codes by using C/C++, Delphi and BCB Borland 
              C++ Builder to invoke the synchronous Application Program Interface (API). |
