  2. End-of-Transmission character - Wikipedia

    en.wikipedia.org/wiki/End-of-transmission_character

    The EOT character is used in legacy communications protocols by mainframe computer manufacturers such as IBM, Burroughs Corporation, and the BUNCH.Terminal transmission control protocols such as IBM 3270 Poll/Select, or Burroughs TD830 Contention Mode protocol use the EOT character to terminate a communications sequence between two cooperating stations (such as a host multiplexer or Input ...

    en.wikipedia.org/wiki/Explicit_Congestion...

    ECN requires specific support at both the Internet layer and the transport layer for the following reasons: . In TCP/IP, routers operate within the Internet layer, while the transmission rate is handled by the endpoints at the transport layer.

  4. XMODEM - Wikipedia

    en.wikipedia.org/wiki/XMODEM

    Since the XMODEM protocol required the sender to stop and wait for an <ACK> or <NAK> message from the receiver, it tended to be quite slow. In the era of 300 bit/s modems, the entire 132-byte packet required 4.4 seconds to send (132 bytes * (8 bits per byte + 1 start bit + 1 stop bit) / 300 bits per second).

  6. Telnet - Wikipedia

    en.wikipedia.org/wiki/Telnet

    Telnet (short for "telecommunications network") [1] is a client/server application protocol that provides access to virtual terminals of remote systems on local area networks or the Internet. [2] It is a protocol for bidirectional 8-bit communications. Its main goal was to connect terminal devices and terminal-oriented processes. [3]

  7. X10 (industry standard) - Wikipedia

    en.wikipedia.org/wiki/X10_(industry_standard)

    Many X10 protocol charts represent this start code as "1110", but it is important to realize that is in terms of zero crossings, not data bits. Immediately after the start code, a 4-bit house code (normally represented by the letters A to P on interface units) appears, and after the house code comes a 5-bit function code .

  8. Secure copy protocol - Wikipedia

    en.wikipedia.org/wiki/Secure_copy_protocol

    The SCP is a network protocol, based on the BSD RCP protocol, [5] which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and uses the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit. A client can send (upload) files to a server ...

  9. KISS (amateur radio protocol) - Wikipedia

    en.wikipedia.org/wiki/KISS_(amateur_radio_protocol)

    The TNC stops processing KISS protocol and returns to its vendor-specific behavior. The command bytes are shown here in Hex , but are sent as bytes, not hex strings. In all cases except the Return command, the high nibble indicates which port (on a multi-port TNC) the command applies to.
