You don't need the development system, and the "debugger" is not some binary
that you would find "lying around". It should be an option in linking your
kernel. I don't know how far SCO varies from the AT&T standard, but if
you run 'kconfig' (or whatever SCO calls the kernel configurer program)
there should be an option to add facilities to the kernel, when you enter
that submenu one of the facilites you can add is the debugger. Then rebuild
a kernel and presto you have the debugger, you can drop into it at any
particular point by hitting <CTRL> <ALT> d, then enter the command:
sysdump. If SCO doesn't include this facility you should scream loudly :-}.

NO. You could use adb on the running system but then 3.2 doesn't have
adb, oh well...
