Subject: re: gdb

I've made some modifications to debug32 to support the gdb "target
remote serial" protocol. I've still got a bunch of testing to do on
it, but I have successfully single-stepped, examined/modified data and
registers and set break points in a program running under a modified
debug32 on a DOS PC from a cross-gdb running on a Sun 4. (The work
will be released when it is tested and reliable, probably with gdb,
and from DJ as well if he wants it.) I believe it is possible to build
gdb on a DOS host for a remote target, so you could use this technique
with two DOS machines...

   I think the answer to this one turned out to be that debug32 was about
   as good as it was getting. Since gdb is a very unix-ish device (running
   and monitoring another process), it would be mostly impossible to port
   to dos. With the improvements to go32 that have been discussed recently,
   a better gdb-ish debugger might be implemented in the future. Again,
   it's all very iffy.
