For a read command, the PHY takes over the MDIO line during the turnaround bit times, supplies the MAC with the register data requested, then releases the MDIO line. When the MAC drives the MDIO line, it has to guarantee a stable value 10 ns (setup time) before the rising edge of the clock MDC.
Several open-source scripts have been developed to facilitate the construction of Python one-liners. Scripts such as pyp or Pyline import commonly used modules and provide more human-readable variables in an attempt to make Python functionality more accessible on the command line. Here is a redo of the above example (printing the last field of ...
The command syntax shows some characters in a mixture of upper and lower case. Abbreviating the command to only sending the upper case has the same meaning as sending the upper and lower case command. [3] For example, the command “SYSTem:COMMunicate:SERial:BAUD 2400” would set an RS-232 serial communications interface to 2400 bit/s.
A command prompt (or just prompt) is a sequence of (one or more) characters used in a command-line interface to indicate readiness to accept commands. It literally prompts the user to take action. A prompt usually ends with one of the characters $ , % , # , [ 15 ] [ 16 ] : , > or - [ 17 ] and often includes other information, such as the path ...
TCSETS exemplifies an ioctl call on a serial port. The normal read and write calls on a serial port receive and send data bytes. An ioctl(fd,TCSETS,data) call, separate from such normal I/O, controls various driver options like handling of special characters, or the output signals on the port (such as the DTR signal).
cu ("call Unix") is a Unix utility for establishing a connection between two computer systems via a serial port to another computer system. When cu was originally created, connections to remote systems were most often done by phone, and cu was used in conjunction with UUCP utilities to transfer data via a modem.
netcat (often abbreviated to nc) is a computer networking utility for reading from and writing to network connections using TCP or UDP. The command is designed to be a dependable back-end that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and investigation tool ...
Asynchronous serial communication is a form of serial communication in which the communicating endpoints' interfaces are not continuously synchronized by a common clock signal. Instead of a common synchronization signal, the data stream contains synchronization information in form of start and stop signals, before and after each unit of ...
