WebDSR (1) (Data Set Ready) An RS-232 signal sent from the modem to the computer or terminal indicating that it is able to accept data.Contrast with DTR. (2) (Dynamic Source Routing) An on-demand routing protocol for wireless networks that uses caches to store routing information.DSR's source routing requires that the sender's packets contain the … Data Terminal Ready (DTR) is a control signal in RS-232 serial communications, transmitted from data terminal equipment (DTE), such as a computer, to data communications equipment (DCE), for example a modem, to indicate that the terminal is ready for communications and the modem may initiate … See more The DTR signal is an important call control signal for a data modem. According to the RS232 standard, dropping DTR from active to inactive for at least two seconds tells the modem to disconnect (end) a call or data connection. … See more On some hardware the DTR line (along with RTS) may be used to provide power. The most notable example of this is a serial mouse. The DE-9 serial port on the PC does not … See more • Ring Indicator See more When a serial connection is made between two computers using a null modem adapter, the DTR and the Data Carrier Detect (DCD) … See more On some printers with serial interfaces, the DTR line is used for hardware flow control, similar to the use of RTS and CTS for modems. This practice is not consistent; other printers define RTS for this same purpose. When DTR is used … See more
WebThe DTR# (Data Terminal Ready) signal of a UART is often used for flow control in modems, but many serial interfaces do not use this signal. It is used to signal that the modem is ready to connect. 2.1.6 DSR# The DSR# (Data Set Ready#) signal of a UART interface is mostly seen in modem applications otherwise the pin is frequently unused. … WebYou can get information about the available serial ports using the QSerialPortInfo helper class, which allows an enumeration of all the serial ports in the system.
