Not sure why it fails with the dtyU0 device.
Maybe because the tests where done using "cat /dev/dtyU0"
throughout this thread. cat(1) itself buffers, defeating
any "stty raw" games to unbuffer the the device. You need
to use "cat -u" when testing with cat(1).
I don't think `-u' matters when cat is writing to a terminal.
(I also suggest "-v" in order to not mess up the terminal with
control codes.)
Yes; or hexdump (but, we aren't seeing anything at all--unless the
device is sending only non-printable chars.--like NULs--which it
isn't. I also converted Ramiro's hexdump output back into binary
yesterday and blasted it to a terminal and _stuff did show up_).
