采用VC6的API函数编写串口程序，实现串口传输数据。-using the API function VC6 prepared serial procedures to achieve serial transmission of data.

这个是用串口下载文件到交界处单片机的代码，而且可以用单片机接收数据用于显示，我们自己使用的工具的-serial download files to the junction of microcontroller code, and SCM can be used for receiving data, we use the tools

一个比较简单的BCB串口源代码，稍微加以改变就可以进行串口的应用了-a relatively simple serial BCB source, a little change can be for the use of Serial

TTL串入并出口74hc164资料 。希望可以用-TTL string into and exported 74hc164 information. Wanted to use

一个串口测试程序，包括源代码，供大家学习-A serial test procedure, including the source code for everyone to learn

The PCD5003A is a very low power decoder and pager controller specifically designed for use in new generation radio pagers. The architecture of the PCD5003A allows for flexible application in a wide variety of radio pager designs. The PCD5003A is fully compatible with “CCIR Radio paging Code No. 1” (also known as the POCSAG code) operating at data rates of 512, 1200 and 2400 bits/s using a single oscillator crystal of 76.8 kHz. In addition to the standard POCSAG sync word the PCD5003A is also capable of recognizing up to 4 User Programmable Sync Words (UPSWs). This permits the reception of both private services and POCSAG transmissions via the same radio channel. Used together with the Philips UAA2080 or UAA2082 paging receiver, the PCD5003A offers a highly sophisticated, miniature solution for the radio paging market. Control of an RF synthesizer circuit is also provided to ease alignment and channel selection
