I've just committed patches to the trunk which allow Tramp to handle
remote ttys. Some simple minded test cases work for me. However, there
are still problems:

The buffer "*input/output of emacs*" shows the error message

&"warning: GDB: Failed to set controlling terminal: Operation not
permitted\n"

Source files seem to be loaded as local files (which works in my case,
because I have used "/ssh::...")

Somebody with more knowledge about gdb (Nick?) might check the issues.

Best regards, Michael.
