WebRTS/CTS, DTR, and DTR/DSR Flow Control. Linux PC's use RTS/CTS flow control, but DTR/DSR flow control (used by some terminals) behaves similarly. DTR flow control (in one direction only and also used by some terminals) is only the DTR part of DTR/DSR flow control. RTS/CTS uses the pins RTS and CTS on the serial (EIA-232) connector. http://www.byterunner.com/16550.html rbc royal bank dealsWebIt is cleared by software (by writing it to 0).
