串行端口,相当于“全双工”端口。 流量控制?
我有一份文档,其中包含通过串行端口与设备的连接信息。 它将“全双工”指定为流量控制设置。 在 Windows 下,我有以下选项用于设置流量控制:
- Xon/Xoff
- 硬件
- 无
上面列表中的“全双工”相当于什么?
I have a document with connection information to a device over a serial port. It specifies "full duplex" as the setting for flow control. Under Windows, I have the following options for setting up the flow control:
- Xon/Xoff
- Hardware
- None
What is the equivalent of "full duplex" in the above list?

“xon/xoff”是“软件流控制”的同义词(与“硬件流控制”相对)。
“全双工”是指“双向”; 理论上,您可以仅在一个方向(即“半双工”)或在两个方向(“全双工”)启用软件流控制或硬件流控制......所以没有足够的信息来回答的问题。
它是什么样的设备? 如果我不得不猜测,我的第一个猜测将是“硬件”流控制,仅仅是因为“软件流控制”在传输二进制数据方面不如“硬件流控制”兼容。
"xon/xoff" is a synonym of "software flow control" (as opposed to "hardware flow control").
"full duplex" means "in both directions"; theoretically you can enable software flow control or hardware flow control in one direction only (i.e. "half duplex"), or in both directions ("full duplex") ... so there's not enough information to answer the question.
What kind of device is it? 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.
