Is software flow control enabled (at least to allow the target to pause sending data)? That is important in D-Bug12 v4.x.x

If that is not the problem, I wonder if there is a set number of bytes you could send continuous, then delay long enough to re-sync bit framing, then continue. That would be if the baudrate is slightly off, and there is too many bit's sent with no distinguishable break.

I agree. I have found a similar problem with HC11
buffalo monitor. For the buffalo, I'm sending a spurious
\0 between each character. This \0 is sometimes received
and sometimes not. The buffalo seems to ignore it.

For Dbug12 I haven't found any such thing. I have very
few information about Dbug12 and it is hard to make a good
monitor frontend in gdb for it.

Can you send me a patch if you have something?

Thanks a lot,
