Specifies additional hardware handshaking settings for serial ports.
PLOTTERMANAGER (Command) Find:
The following options are displayed.
Enables Clear To Send handshaking. This monitors pin 5 of a 25-pin serial port or pin 8 of a 9-pin serial port. CTS is an input bit, monitored for an output from the plotter or printer.
Enables Data Set Ready handshaking. This monitors pin 6 of a 25-pin serial port, or pin 6 of a 9-pin serial port. DSR is an input bit, monitored for an output from the printer or plotter.
Enables Received Line Signal Detector handshaking. This is sometimes called DCD or Data Carrier Detect. It is an input pin that can be monitored for an output from the plotter. It is on pin 8 of a 25-pin serial port and on pin 1 of a 9-pin serial port.
Controls the Request To Send output bit. This sends a signal to the printer or plotter on pin 4 of a 25-pin serial port or on pin 7 of a 9-pin serial port.
Disables the RTS line when the device is opened.
Enables the RTS line when the device is opened.
Enables RTS handshaking. The driver raises the RTS line when the input buffer is less than one-half full and lowers the RTS line when the buffer is more than three-quarters full.
Specifies that the RTS line is high if bytes are available for transmission. After all buffered bytes have been sent, the RTS line is low.
Controls the Data Terminal Ready output pin. This sends a signal to the printer or plotter on pin 20 of a 25-pin serial port or on pin 4 of a 9-pin serial port.
Disables the DTR line when the device is opened.
Enables the DTR line when the device is opened.
Enables DTR handshaking.
