Serial Communication
The start bit is a logical 0 sent on the line to tell the other
device to start sampling.
RS-449 (a functional and mechanical interface that used RS-422 and RS-423
signals - it never caught on like RS-232 and was withdrawn by the EIA)
MIL-STD-188 (a system like RS-232 but with better impedance and rise time
control)
Other serial interfaces similar to RS-232:
