测试传感器温度的控件...实在没什么可多介绍的了.VC-test temperature sensor controls ... nothing can introduce more of it. VC

2005-7-13 10:03 前几天要做一个短信收发的小软件，于是按照习惯Box寻找例程和控件，可惜没有找到！ 于是,大幅翁、Google!!!终于找到了好几个，不是要收费就是不能用！气愤！！ 这又不是什么高新尖端科技，俺们不是做不出来,俺们只是秉承RAD的精神而已！ 于是这个短消息控件诞生了！虽然还很简陋，起码胳膊腿都有了，剩下就看它怎么跑了！ 使用标准AT指令 现在只能支持PDU模式（Text模式太简陋）！ 支持7_Bit 和 UCS2 编码 集成了串口（spcomm） 只需要简单的配置几个参数就可以收发短信了-2005-7-13 10:03 A few days ago to be a small message to send and receive software, then in accordance with the customary Box search routines and controls, but did not find! Thus, a substantial Weng, Google!!! Finally found a few, not a fee is not! Angry! ! This is not a high-tech state of the art technology, not俺们not able to,俺们only uphold the spirit of just RAD! So the short message control was born! Although very simple, at least arm leg with the rest look on how it ran! Using standard AT commands can now only support PDU mode (Text model is too simple)! Support the UCS2 coding 7_Bit and integrated serial port (spcomm) only need a few simple parameters can be configured to send and receive a message

rs232编程原理详解， 不可多得的一本好书 做硬件开发必须-Detailed programming rs232 principle, rare books to do a hardware development to be

一个包含了几乎所有串口操作的源码群，可以根据自己需要改写-1 contains almost all serial-source operating groups, according to their own needs rewriting
