The availability of the nic cannot be guaranteed since the machine is
being configured on one netblock and then being physically transferred to
a distant location. It is entirely possible that whatever IP address is
assigned to the eth0 connection here as being the one that will be used
there may not actually work on the target network.  The purpose of the
serial connection is to permit a laptop to substitute for a
monitor/kb/mouse on site in that eventuality.  If it proves too cumbersome
to enable direct host to host communications via usb then we will simply
ship a 15" flat screen, kb and mouse with the unit and have them returned

We could, I suppose, reconfigure the available serial port as a tty and
then connect that way, establish network connectivity, detach, and
reconfigure the DB9p as an STTY for the fax service.

Thank you for the cable suggestion.  I will look into that.
