- 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*
- Chop off the end that connects to the phone (NOT the USB end)
- Connect the wires to JP8 on the CX910 Board or JP4 on the C710 Board as follows
- Yellow (RX) to Pin 5
- Blue (TX) to Pin 7
- Brown (DCD) to Pin 9
- Orange (CTS) to Pin 13
- 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).
