Re: unable to switch to plain text mode

I've also written a simple character mode debugger which does something
similar using ptys.  The difficulty is making the pty code portable (I
actually wound up stealing it from librxvt).  Once you have ptys, you can
run external programs through this, read the output from a file stream
(similar to pipes, but looks like a terminal to the running program), and
display it sensibly.

The downside is that you tend to have to select from the various input
channels to do I/O properly.

If you're interested in the code, let me know.
