UARTs when their divisor latch registers are selected while they are doing output. Waiting for (some) output to drain is not permitted for the TCSANOW case of tcsetattr(). NIST-PCTS easily detects bugs like this by testing at at speeds that no one would want to use (50 bps). Deleted stale comments related to flushing i/o. Flushing works properly for 16550s according to NIST-PCTS (it can't work properly for 16450s). This finishes fixing all sio(16550)-related bugs found by NIST-PCTS. |
