串行端口，等同于“全双工”流控制？

[英]Serial port, equivalent of “full duplex” flow control?

I have a document with connection information to a device over a serial port. 我有一个文档，其中包含通过串行端口到设备的连接信息。 It specifies "full duplex" as the setting for flow control. 它指定“全双工”作为流量控制的设置。 Under Windows, I have the following options for setting up the flow control: 在Windows下，我具有以下用于设置流控制的选项：

Xon/Xoff XON / XOFF
Hardware 硬件
None 没有

What is the equivalent of "full duplex" in the above list? 上面列表中的“全双工”等效项是什么？

"xon/xoff" is a synonym of "software flow control" (as opposed to "hardware flow control"). “ xon / xoff”是“软件流控制”的同义词（与“硬件流控制”相对）。

"full duplex" means "in both directions"; “全双工”是指“双向”； theoretically you can enable software flow control or hardware flow control in one direction only (ie "half duplex"), or in both directions ("full duplex") ... so there's not enough information to answer the question. 从理论上讲，您只能在一个方向（即“半双工”）或两个方向（“全双工”）上启用软件流控制或硬件流控制。因此，没有足够的信息来回答这个问题。

What kind of device is it? 这是什么设备？ If I had to guess, my first guess would be "hardware" flow control, simply because "software flow control" is less compatible than "hardware flow control" with transferring binary data. 如果不得不猜测，我的第一个猜测将是“硬件”流控制，这仅仅是因为“软件流控制”与“硬件流控制”在传输二进制数据方面的兼容性较差。
