Yes. This is simple.

And this is not clear to me, I need your help ;)

What should ugdb know about breakpoints? I played with the real
gdbserver, and afaics gdb just changes the tracee's memory and
inserts 0xcc (int 3). But gdb.info mentions "Z TYPE,ADDR,KIND"
packets.

So, what should ugdb do? Just implement memory write (M or X)
and then report SIGTRAP like gdbserver does?
