I just upgraded from 7.2-stable to 8.0-stable, same kernel config (with

Everything worked before, with the same serial port settings, uart device
etc. Has anything else changed in the serial interface? I'm using the cuauX
devices at 2400 baud.
For some low speed apps (1200bps in our case) I found I needed to set
hint.uart.0.flags="0x00100"

Thanks for the suggestion. 0x100 doesn't seem to work, no data is being
seen at all. Using 0x800, I get a bit more data, and if I slow down how
fast I'm reading from the port I get a bit more (?????), but the final
pass only reads two bytes before hanging indefinitely, not honoring the
VMIN/VTIME parameters. It's almost like data is being thrown away, but the
actual number of bytes is very small so I don't see how that could be
happening.
