通过串口监测TDRAM是否正常工作的程序。-through serial monitoring TDRAM normal working procedures.

本程序是i2c总线读写一个字节的程序。在写过程序中，不一定非要检测i2c的应答位，可以直接延时过去就行，但是在读过程中必须给应答信号，读完发停止位，一定确认所发的信号都发上了。否则在连续地址读的过程中可能不会出错，但是在随机度过程中就会出错，我的程序就是在给停止信号时没有给上，24cxx一直在输出数据，结果读出错。找着问题后我的程序只加入了一条命令便完全正常。-i2c bus read and write a byte procedures. The written procedure, not necessarily require the detection i2c-response, and can directly past trip delay, but the process must be read to the response signal, stopped at reading, we recognize the signals are on the fat. Otherwise, the address read for the course could not go wrong, but the randomness of the process would be a mistake, I was in the process to stop for no signal, 24cxx in output data, read errors. I discovered the problem after the procedure just joined the order of a completely normal.

GSerial是一个DOS下串口通信程序，程序结构较好，能编出用中断方式接收/发送的多串口通信程序（龚建伟曾用它编过7串口通信程序）。Turbo C++ 3.0 Dos或 Win3X/9X/ME/NT/2K的DOS环境下运行-GSerial under DOS is a serial communication program, program structure better, can be compiled out with interrupt receiving/sending of multiple serial communication program (Dan has used its seven series serial communication procedures). Turbo C 3.0 Dos Win3X/9X/ME/NT/2K or the DOS operating environment
