Description: The UART (Universal Asynchronous Receiver/Transmitter) core provides serial
communication capabilities, which allow communication with modem or other external
devices, like another computer using a serial cable and RS232 protocol. This core is
designed to be maximally compatible with the industry standard National
Semiconductors’ 16550A device.

Description: 单片机RS232/RS485串行发送实验（双机通讯）。
实验步骤：
（1），准备两台598K实验机，确定1号机为发送，2号机为接收；
（2），当作RS232接口实验时，1号机和2号机的P3.0和P3.1交叉相连，且两机共地；
（3），当作RS485接口实验时，1号机和2号机的A、B作对应连接，同时1,2号机的R/TEN接P1.0, P3.0接R0, P3.1接DI。
（4），先运行2号机，键入[27]-->[EV]使2号机处于接收状态P。，后运行1号机[26]-->[EV]使1号机处于发送状态,P。会闪烁，在1号机键盘上按动数字键，在2号机的数码管上应显示对应的数字键值。

Description: STC11/10xx系列单片机是宏晶科技设计生产的单时钟/机器周期(1T)的单片机，是高速、低功耗、超强干扰的新一代8051单片机，指令代码完全兼容传统8051，但速度快8-12倍。内部集成的FLASH寿命可达10万次，并且完全支持ISP和IAP功能。该系列针对不同功能、电压、封装等的型号规格非常齐全。所有的STC11/10xx系列单片机内部都固化了宏晶科技的ISP程序，不需要并行编程器，通过RS232串口就可以烧录用户程序。但一些系统为了程序保密或者采用其他诸如RS485通讯或其他通讯方式的需要，仍然需要自己编写ISP程序用于系统升级。在STC11/10xx系列单片机中以IAP打头的芯片型号，用户程序和数据FLASH是统一寻址，允许在用户程序中擦写FLASH，因此可以编写自己的ISP程序。
本程序例子中选用的单片机是IAP11F62X，包含内部可用的62kFLASH空间和扩展的1024字节XRAM。-STC11/10xx MCU is a macro technology design and production of single-crystal clock/machine cycle (1T) of the microcontroller, high-speed, low power, interference of a new generation of super-8051 microcontroller, instruction code is fully compatible with the traditional 8051, but the 8 speed-12 times. FLASH integrated within the life of up to 10 million, and fully support the ISP and IAP capabilities. The series for different functions, voltage, packaging model specification is complete. All STC11/10xx MCU are cured within a macro crystal technology, ISP program, does not require parallel programming device, can burn through the RS232 serial port on the user program. However, some systems used to process confidential or other communications such as RS485 or other communication needs, still need to write your own ISP program for system upgrades. In STC11/10xx MCU starts with the chip in order to IAP model, the user program and data addressing FLASH is unified, allowing users to program

Description: 使用RS232接口（pc机COM口）
PC启动等待不少于10秒
POS机发送"Q",PC收到返回“R”
POS接收后发送最后一条记录的地址号（序号）
PC收到发回传送记录的首地址
pos机按接收到的首地址开始发送10条记录
pc每接收完8个字符（8个字节数据）返回一个“C”，10条记录（160个字符）完成后返回“E”
PC收到“C”继续发送，收到“E”结束本次发送
