bisync การใช้

• Multi-drop is part of the initial Bisync protocol.
• Some important systems use Bisync data framing with a different link control protocol.
• CCL does not support Bisync or start-stop.
• In Bisync, the NAK is used to indicate that a retransmission of that block.
• At one time Bisync was the most widely used communications protocol and is still in limited use in 2013.
• Binary Synchronous Communications ( Bisync ) and Adaptive Link Rate ( for Energy-Efficient Ethernet ) is an example.
• Bisync does not use a single ACK character, but has two control sequences for alternate even / odd block acknowledgement.
• VTAM supports several network protocols, including Bisync, local ( channel attached ) 3270 devices, and later TCP / IP.
• Higher-level protocols included BiSync, HDLC and SNA, without the need for the host CPU to handle these details.
• Two adapter versions were available, one for Synchronous transmit-receive ( STR ) and one for binary synchronous communications ( Bisync ).
• Teleprocessing monitors such as IBM's CICS and third-party software such as Westi platforms used Bisync line control to communicate with remote devices.
• Since Bisync data packets are not serial-numbered, it's considered possible for a data frame to go missing without the receiver realizing it.
• Telenet supported remote concentrators for IBM 3270 family intelligent terminals, which communicated, via X . 25 to Telenet-written software that ran in Bisync protocols.
• IBM Input / output devices utilizing the Bisync link protocol use the "'SYN "'character code to signal the beginning of each data frame transmitted.
• Interfaces to these networks include TCP / IP and UDP, X . 25, asynchronous protocols and several synchronous protocols, such as SDLC, HDLC, Bisync and others.
• Some early X . 25 networks tolerated a connection scheme where transparent Bisync data frames encapsulated HDLC LAPB data and control packets ., several vendors encapsulate Bisync transmissions within TCP / IP data streams.

• This macro specified the line characteristics & mdash; start-stop, bisync, point-to-point, multipoint, leased line or dial & mdash; and the type of " polling " required & mdash; wrap around or open.
• Houston Automated Spooling Program ( HASP ) uses Bisync half-duplex hardware in conjunction with its own link control protocol to provide full-duplex multi-datastream communication between a small computer and a mainframe running HASP . In Bisync terms, this is " conversational mode ".
