Sorry, which part of the paragraph below the picture is unclear to you? ============== On the C123 the following pads are usable * TP27 -- DLPWR (download power on), connects to Iota:RPWON * TP14 -- RxD Modem * TP13 -- TxD Modem * TP9 -- CTS Modem * TP39 -- GND On most phones other pads are grounded and not usable (like in the scan above). Known exceptions * C115 and C117 have all test pads * C155 has JTAG but not IRDA UART test pads ============== Regards, Harald -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
