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 printers with serial interfaces, the DTR line is used for hardware flow control, similar to the use of RTS and CTS for modems. This … 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) lines are typically paired. This allows both ends of the connection to sense when the connection is active. On many operating … 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 provide … See more sehore crescent water park
