Christophe Devine devinechristophe at gmail.comCraig, I identified the pinout on the C139, it is somewhat different. On the right, you have now: TX|DLPWR|CTS|RX|GND; this is the modem UART +DLPWR. Irda and JTAG are removed. You can use DLPWR to automatically start the phone by forcing it low. Btw on the C115/C118, you can use nSRST to fully reset the board with a relay (to do so, you will need to modify a battery as I explained in an earlier post). The modem UART is not really necessary unless you plan on debugging the official firmware.
