Jim,
I'm using TeraTerm version 2.3.
I've also occasionally used TeraTerm successfully. Usually, I use the
Linux "cu".
I can send Ctrl-C the board. However when I'm in this looping mode I can't.
I have no other ideas for you to try, I'm sorry.
Perhaps, looking at the networking retry code for your version will
reveal if it watches for interruption.
From what you descried, version 2010.12 works and maybe I should update to a
later version and see if that fixes my issue.
The common advice given on the mailing list is to update to a later
version. Once you are running a relatively recent version, help is more
likely to be available.
Since most developers on the mailing list are running something very
recent, it can be difficult to help with older versions.
If you are going to update, choose something more recent than 2010.12,
maybe something from 2013 or 2014.
Perhaps, as you hope, a newer version will fix your problem.
Thanks
Dang
Good luck.
Jim

Hi James,
I'm using U-Boot 2010.06 (Jun 18 2013 - 14:03:16)
This is a version of U-Boot that is even older than the version I used for my
demonstration that ctrl-c works. (I used 2010.12)
You should make efforts towards using a more recent version.
What information can you provide as to the settings of your serial terminal
emulator? Is it known to send your ctrl-c to the target device?

Hi,
I'm running a PowerPC board that uses U-Boot and I get into this loop (see
terminal output below).
It doesn't matter how I get into this loop. What I really care about is how to
break out of it without manually resetting the board.
Is there a way to break out of this loop and reset the system via the terminal?
Ctrl-X and Ctrl-C doesn't seem to do anything.
It might be helpful to know which version of U-Boot you are using.

Please make sure your serial communication terminal emulator correctly transmits the
ctrl-C when you type it. To see if this works, get to a U-Boot prompt and type
ctrl-C, you should see <INTERRUPT>
