Questions tagged [serial]
is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. Traditionally "serial" relates to a three (or more with hardware handshaking) wire system (TIA-232-F), now using ∓25V Voltages. Technically speaking the specialized SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit) buses are serial communication systems as well - use one of those tags if they would be more appropriate!
