Debug How to

[Joe Samuel]

I also agree that Eric Norum's mail was more than
helpful to me, but still I'm got stuck somewhere. The
remote debugger stub prints out messages to indicate
that it has been started on COM2. But when I tried to
connect to it from my Linux host, nothing works.
I used
#i386-rtems-gdb -b 38400

  >target remote /dev/ttyS1

Then GDB just keeps mum. When I press cntrl+c it says
could not connect to remote target. 
  I ensured the physical link using miniterm. What
should be wrong with gdb? Can anyone help out?
thanks
Joe
