Problem with gdb/mi under hp-ux 11.11, aix 5.2, gdb 6.7.1

Hallo,

I am trying to get ccdebug <http://ccdebug.sourceforge.net/>, a Qt-based
gdb frontend to work on hp-ux. It works without problems on linux. On
hp-ux, though, and also on aix,
I am having trouble when I hit the key to show the register values. The
funny thing is, sometimes it works, but mostly it does not, i.e. there is no
response from the forked gdb, because otherwise I would see it in the log.
The following command is sent to gdb, but no response arrives.

^[[46mSent: -data-list-register-values x ^[[0m

What can this be and how can I test this?

Also, when I try to debug ccdebug with gdb directly, I get a ttrace:
Protocol error.
Attaching to the running process also does not work.
