Greg, This is happening on RHEL4 kernel 2.6.9-42 I believe. SMP and non SMP. I can give a better explanation:
I have a null modem cable going from ttyS0 (the regular serial port on the box) to ttyUSB0 in one xterm, I open minicom edit it to use USB0, etc. In the other xterm, I cat a text file that is nothing but 1234567890 to ttyS0. It goes through fine, many times. Then I exit minicom, restart minicom, and in this case, the first time I cat the same file to ttyS0, in minicom (USB0) it shows up minus the first character, such as 234567890 showing up the first time when I send 1234567890 to ttyS0, but subsequent cats to ttyS0 show 1234567890 just fine. Why is it dropping this character, and why is it only when I exit minicom, and then restart it?
