I have a development board with a CP2105 on it, and I was trying to send a break to it to do a sysrq. And it wasn't working. I have verified that the target driver works by setting a really slow baud rate and sending something with a lot of zero bits. It got breaks just fine. If I use TCSBRK, it seems to just send a short time with zeros, not even a full character's worth. It receives a valid character with the top few bits set. If I use TCSBRKP with a longer time, like 2.5 seconds, it waits the whole time, then at the very end it gets the character as with the shorter break. I can't find a programming manual for the chip, and I'm not sure what's going on. -corey
