#105734 - faulty UART Responding to: ???'s previous message |
While I don't know how to exhaustively test the UART/protocol robustness, I know of a defective UART (in superIO of certain brand, often found in common PCs), receiver of which sticks when subjected to train of random pulses of length shorter than the programmed bit length.
The trouble here is of course in the silicon, so such test is probably not needed for an application engineer, but an example of what has one to examine when the application stops unexpectedly... Jan Waclawek |
