Access Serial Port

1. Obtain Futuredial LG5350 Cable USB->Serial cable that uses TTL levels rather than RS232 levels such as which I got for $10 from Radio Shack*
2. Chop off the end that connects to the phone (NOT the USB end)
3. Connect the wires to JP8 on the CX910 Board or JP4 on the C710 Board as follows
   1. Yellow (RX) to Pin 5
   2. Blue (TX) to Pin 7
   3. Brown (DCD) to Pin 9
   4. Orange (CTS) to Pin 13
4. Plug the USB Cable into your computer and start a shell on the serial port

To start the shell, you can get my working busybox from http://www.phathack.com/busybox.bz2 then use the following to start it on the serial port. See HOWTO: Run Unsigned Code

/dos/busybox mv /bin/busybox /bin/busybox-old
/dos/busybox ln -s /dos/busybox /bin/busybox
/bin/busybox --install -s
(sh < /dev/ttyS0 > /dev/ttyS0 2> /dev/ttyS0 &)

• This cable needs to have a "bulge" in the middle of it. Radio Shack sells all sorts of Futuredial cables. The cable tested here is described as "LG 1010, 5350, VX1 and VX10" and has product number 170-0783 (above the UPC on the back).
