By default, the root is the device owner, with both read and write permissions.That is why it seems easier to just use root credentials to use any device, serial ports included. Needless to say that writing to the wrong device can be quite dangerous. For instance, writing to a device li...

Virtual serial ports are a logical representation of physical serial ports. These ports don’t connect with the serial port. A virtual serial port allows us to emulate a physical serial port, thereby removing the requirements of cable and physical communication interface. Additionally, a virtual por...
A virtual serial port is a redirector without network software support which is usually used to create a pair of back-to-back virtual COM ports on the same computer. Two legacy applications can then communicate using virtual serial ports instead of conventional inter-process communication mechanisms ...
Older RS-232 type and similar serial ports are special terminal devices. You can’t do much on the command line with serial port devices because there are too many settings to worry about, such as baud rate and flow control. 旧的RS-232类型和类似的串行端口是特殊的终端设备。 你无法在命令行...
