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 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 'Data Terminal Ready' signal for the serial data transfer is set here. Possible values are summarized in the enumeration ComDTRCtrl_t. CTS. The 'Clear to Send' signal for the serial data transfer is set here. If the value is TRUE, no data are sent if the CTS input signal for the data transfer is not set. DSR WebIt is thus highly recommended that the virtual serial line DTR (Data Terminal Ready) signal be used where possible to determine if a host application is ready for data. So the DTR signal was mandatory and all I had to do was to add this to the interface configuration: connection.controlTransfer(0x21, 0x22, 0x1, 0, null, 0, 0);
WebThis option is the default. With this option, pppd will wait for the CD (Carrier Detect) signal from the modem to be asserted when opening the serial device (unless a connect script is specified), and it will drop the DTR (Data Terminal Ready) signal briefly when the connection is terminated and before executing the connect script.

WebWhen the interface MCU receives a Data Terminal Ready (DTR) signal from a terminal, it performs automatic Hardware Flow Control (HWFC) detection.. Automatic HWFC detection is done by driving P0.21 (Clear to Send (CTS)) from the interface MCU and evaluating the state of P0.19 (Request to Send (RTS)) when the first data is sent or received.If the state …
