WebPin change interrupts are usually not a good way to detect button actions. This is because mechanical buttons bounce, and you will get lots of meaningless interrupts, and then you still have to do debouncing anyway. A better way is to have a periodic interrupt, like every 1 ms (1 kHz rate). That's a long time on most processors, so the fraction ...

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.
