  2. Automatic baud rate detection - Wikipedia

    en.wikipedia.org/wiki/Automatic_baud_rate_detection

    Automatic baud rate detection (ABR, autobaud) refers to the process by which a receiving device (such as a modem) determines the speed, code level, start bit, and stop bits of incoming data by examining the first character, usually a preselected sign-on character on a UART connection. ABR allows the receiving device to accept data from a ...

    Each test measures the data rate for the download direction, i.e. from the server to the user computer, and the upload data rate, i.e. from the user's computer to the server. The tests are performed within the user's web browser or within mobile apps. As of 17 February 2024, over 52.3 billion Internet speed tests have been completed. [8]

  5. Measuring network throughput - Wikipedia

    en.wikipedia.org/wiki/Measuring_network_throughput

    When talking about circuit bit rates, people will interchangeably use the terms throughput, bandwidth and speed, and refer to a circuit as being a '64 k' circuit, or a '2 meg' circuit — meaning 64 kbit/s or 2 Mbit/s (see also the List of connection bandwidths). However, a '64 k' circuit will not transmit a '64 k' file in one second.

    The Hayes command set (also known as the AT command set) is a specific command language originally developed by Dale Heatherington and Dennis Hayes [1] [2] for the Hayes Smartmodem in 1981. The command set consists of a series of short text strings which can be combined to produce commands for operations such as dialing, hanging up, and ...

    en.wikipedia.org/wiki/Voice_modem_command_set

    The command AT+FCLASS=8 or AT#CLS=8 will put the modem in voice mode. Most modems still remain on-hook and respond with OK. Once this command has been accepted, most modems will respond with Data Link Escape (DLE) messages instead of or in addition to normal modem responses.

    cmd.exe is the counterpart of COMMAND.COM in DOS and Windows 9x systems, and analogous to the Unix shells used on Unix-like systems. The initial version of cmd.exe for Windows NT was developed by Therese Stowell. [6] Windows CE 2.11 was the first embedded Windows release to support a console and a Windows CE version of cmd.exe.

  9. Batch file - Wikipedia

    en.wikipedia.org/wiki/Batch_file

    In MS-DOS, a batch file can be started from the command-line interface by typing its name, followed by any required parameters and pressing the ↵ Enter key. When DOS loads, the file AUTOEXEC.BAT, when present, is automatically executed, so any commands that need to be run to set up the DOS environment may be placed in this file.
