[Elphel-support] netboot script errors out

[Brian Burke]

Eureka!  Well, before I was able to get a tool that would allow me to access
the RS232 port, I tried getting the camera into netboot mode a few more
times - and I finally got it.  I guess it was just a matter of getting the
"3 count" right.  Once I got past that, I was able to update the firmware.

Thanks for all the help.
