hi all: if there are many usermode program try to open /dev/ttyS1 for example and read/write the /dev/ttyS1 at the same time. Did kernel tty driver so far handle the race condition above not to let the message interleaved? such as user A --> send "abcd" --> ttyS1 user B --> send "1234" --> ttyS1 how to make sure the serial Tx of ttyS1 will send either "abcd1234" or "1234abcd" sequencially instead of "a1b2c3d4", etc. appreciate your kind explaination in advance, -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
