Hello,
I'd like to detect BREAK conditions on the built-in SIO of an Atmel AT91RM9200 ARM processor. No matter which way I set all those stty flags (PARMRK, BRKINT, IGNBRK, IGNPAR etc.), I don't manage to read breaks as anything except 0x00 bytes, which is obviously no good. Only when I set parity enabled and odd parity I see the expected 0xff 0x00
0x00 sequence, but that's because a break is also a parity error in odd parity, and it's no good since I don't want to use parity.Has anybody managed to actually see breaks on the SIO with this chip?
Any help appreciated,
