串行端口(Serial port) & EIA-RS-232 串行端口(Serial port),或称串行埠、序列埠、串口,主要用于串行式逐位元数据传输。常见的为一般电脑应用的RS-232(使用 25 针或 9 针连接器),工业电脑应用的半双工RS-485与全双工RS-422。 串口叫做串行接口,也称串行通信接口,按电气标准及协议来分包括RS-232-C、RS-422...
EIA 232是 8 端口异步适配器,提供了对连接最大 8 个 EIA 232D 异步串行设备(例如调制解调器、终端、绘图仪和打印机)到系统部件的支持。 系统必须基于 Micro Channel 总线或 ISA 总线,并且最多支持 8 个 8 端口适配器。 此适配器是完全可编程的,且只支持异步通信。 它还可以添加和删除起始位和停止位,且在...
To correct this accounting (but not always fix the problem) you may use “setserial” to change the baud_base to the actual maximal speed of your port such as 230.4k. Then if you set the speed (by your application or by stty) to 230.4k, a divisor of 1 will be used and you’ll ...

I've purchased a used BayTech RPC4 unit (8-port power strip controllable using RS232). The front of the unit has an RJ45 port (EIA-232) and has a wiring diagram on how to wire it to a DB9 port so you can connect it to a PC. Here's the diagram: If I u...
在过去的十年中,随着PC的出现和COMPort的增多,使得机器用具制造商开始坚持使用一个普遍的标准,那就是 DB-25-P连接器的使用,它通常与计算机上的接口配合使用。 本文不是用来定义RS232的每一个细微之处而是解释它的基本功能和使用,从而给予任何需要安装RS232接口 ...
