This is an old one. My original post:

I got this response from Barry Treahy <treahy_at_allianceelec.com>:

Is this a new DS700 or used?  If used, I recommend doing a factory reset on it.
Power off, press and hold the little button next to the power cord and reapply
power holding the button.  After about 15 seconds, or until you see an E in the
LED, let go.  This will then restore the factory settings, including the
privileged password.  Once done, connect a terminal or PC with a terminal
emulator (I'd use something, anything else that your DU box) to PORT 1 and set
the buad to 9600, 8-bit no parity.  At that point, you should be able to see
everything.  If you can tell me what the LED is stopping at, I can probably tell
you what it is, but my guess is that you do not have your tftp deamon configured
properly to handle the OS download...

  Hi there. 
  
  1. Use tip instead of cu.  
  2. Add the following to the /etc/remotes file.
  remote:dv=/dev/tty01:br#9600:
  then the following will work:
  $ tip remote <CR> <CR>
 
  And you should get a console for the other machine.

Unfortunately, I couldn't get it working on the Alphaserver.  I finally
got it working via a PC.  I'm still not clear on what I need to do to 
get it working on the AlphaServer.  What about the flow control for the 
device and other options that can be configured on the EPROM?
Thanks!
