从C#中的串行端口读写，第2部分

我正试图用C#1程序取代C程序。C程序通过COM1串行端口连接到旧计算机。我没有任何关于C代码如何连接到另一台机器的信息，但它确实正确连接，所以我不得不猜测它是如何连接的。我一直在用它来试图弄清楚C程序是如何成功地编写和读取的。当我的新C#应用程序运行时，我也一直在运行Portmon。在我的C#程序中，我使用SerialPort类

我试图通过在工作程序上使用Portmon的输出来确定SerialPort类中的不同项应该具有哪些值。我的想法是，如果我能为类获得正确的值，它就会正确地写和读。程序（如下）工作不正常。程序成功打开COM1端口，但在尝试写入一个周期（然后是另一个周期）时失败。这会给你一个暂停时间

查看运行在旧C程序后面的Portmon的输出，工作程序打开COM1端口，然后在从COM1端口读取成功值（&OK）之前先写入一个句点，然后再写入另一个句点。旧程序设置了几个我想在C#程序中复制的值

我已经尝试了下面各种SerialPort选项的组合，但我显然什么都没想到

顺便说一句，我在堆栈溢出问题中问了一些初步问题

我在运行程序的机器上使用Windows XP。COM1端口另一侧的机器是一台非常旧的PC

有更好的方法吗？使用Portmon以外的其他工具？对于旧程序的Portmon输出，进程列为ntvdm.exe。这是个问题吗？我不应该使用C#SerialPort类吗最重要的问题可能是：Serialport类应该使用什么值来匹配旧程序？

我的C#计划：

下面是我正在创建的C#应用程序的Portmon输出。上面的C#代码在后台使用Portmon运行时会创建此输出。我把标题放进去

如您所见，在写入过程中，第69行出现超时错误。我需要它运行得足够接近C语言，这样写和读就可以工作了

很明显，波特率、字长、奇偶校验和其他几个设置都是正确的

PortMon输出一个句点作为\n.

检查并读取StopBits.One。1 != 停车位。One@gabba我不明白那个评论。停车位怎么样，一号！=1.它不等于1什么？它当然等于1个停止位。您还没有花太多的精力使PortMon输出在两个程序之间匹配。关键的不匹配是握手属性。@gabba我只看到0不是有效的。你在找什么？我找到的链接是@Jim好的，我明白gabba的意思，但这不适用于这里。停止位。一个枚举值如果转换为int，则为0。但这不是你要做的，所以这个评论并不适用。您正在将SerialPort.StopBits（这是StopBits枚举属性）设置为StopBits.One，这正是您应该执行的操作。
