Abstract
A special data including communication wire continuous dominant levels of a number of N more than the transceiving bit number of n of communication wire continuous dominant levels, set in a character as one unit of communication data, can be transceived by a widely-used serial communication interface such that a predetermined transmission rate is changed to n/N times the transmission rate only when the special data is transmitted, whereby the special data can be easily transceived at a low cost.
Claims12
A method for transmitting communication data at a predetermined transmission rate by Universal Asynchronous Receiver/Transmitter (UART), the method comprising:
- only when a special data having a bit number of N more than a transceiving bit number of n, set in a character as one unit of the data, is sent, changing the predetermined transmission rate to n/N times the predetermined transmission rate.
A device for transmitting communication data, the device comprising:
- a data control unit for transmitting the data at a predetermined transmission rate by Universal Asynchronous Receiver/Transmitter (UART) and a serial communication interface for transmitting the data from the data control unit to a communication wire, wherein only when a special data having a bit number of N more than a transceiving bit number of n, set in a character as one unit of the data is sent, the predetermined transmission rate is changed to n/N times the predetermined transmission rate.
A method for transmitting communication data at a predetermined transmission rate by Universal Asynchronous Receiver/Transmitter (UART), the method comprising:
- when an intercharacter time is required between characters, which are one unit of the data, transmitting the data after adding a bit number satisfying the intercharacter time to a stop bit number in the characters defined on a transceiving side, wherein the characters together with the added bit number are transmitted in a communication frame.
A device for transmitting communication data, the device comprising:
- a data control unit for transmitting the data at a predetermined transmission rate by Universal Asynchronous Receiver/Transmitter (UART) and a serial communication interface for sending the data from the data control unit to a communication wire, wherein when an intercharacter time is required between characters, which are one unit of the data, the data are transmitted after adding a bit number satisfying the intercharacter time to a stop bit number in the characters defined on a transceiving side, wherein the characters together with the added bit number are transmitted in a communication frame.
A method for transmitting communication data at a predetermined transmission rate by Universal Asynchronous Receiver/Transmitter (UART), the method comprising:
- transmitting data comprising a plurality of characters in a communication frame,
- wherein, each of the plurality of characters is one unit of said data,
- wherein said one unit of data comprises at least one stop bit, and
- wherein, when an intercharacter time is required between said plurality of characters, prior to said transmission, adding a bit number satisfying the intercharacter time to said at least one stop bit,
- wherein said one unit of data further comprises the intercharacter time.
