如何将数据从驱动程序发送到串行端口 [英] How to send data from driver to Serial port

问题描述

大家好！

我想问一下从驱动程序向COM端口发送数据的问题。

例如：

我从我的程序发送一个号码给我的司机。收到号码后，我的驱动程序加1，然后发送到连接到Serial2的Serial1。在终端我希望看到我的号码+1。类似的东西...



如何从驱动程序向COM发送任何内容？

Hi all!
I would want to ask u a question about sending data from driver to COM-port.
For example:
I send a number from my program to my driver. After receiving the number, my driver adds 1 to it and sends to Serial1 that is joined to Serial2. In terminal I expect to see "my number"+1. Something like that...

How can I send anything from my driver to COM?

推荐答案

我希望我的驱动程序在激活驱动程序时在串口发送一些符号'A'。

如果我不知道怎么办，我应该发布什么信息？我可以从驱动程序发送数据到应用程序，可以触摸驱动程序到串口，但不知道如何发送任何东西...（这些驱动程序的代码，我可以发布）

I want my driver to send some symbol 'A' in Serial port when driver is activated.
what information should i post if i have no idea how to do it? i can send data from driver to application, can touch driver to Serial port, but dont know how to send anything to it...(code of these drivers i can post tho)

尝试发布一个代码片段。没有人可以从那些告诉我们什么的信息中帮助你。

Try posting a code snippet .. no one can help you from that information which tells us nothing.
