Hi all, Some fixes related to power-up/power-down some modems are available in the 'power-up-check-needed' branch in the following Gitorious repo [1]: git://gitorious.org/lanedo/modemmanager.git
The changes being: * Modified the generic GSM implementation so that we allow plugins to check whether they need a power-up command. If plugins reply saying they don't need it, the power-up command is skipped. * Added a new property in the Serial Port object to (try to) enable RTS/CTS flow control mode in the serial line. * Wavecom: Check whether the modem is in full-functionality mode (AT +CFUN: 1), and if so, avoid sending the power-up command. * Wavecom: Use AT+CFUN=4 to go to standby/low-power mode. * Wavecom: Use AT+CFUN=1,0 to power-up the modem (only when not already in full functionality mode) * Sierra: Check whether the modem is in full-functionality mode (AT +CFUN: 1), and if so, avoid sending the power-up command. This should fix LP#459052 [2], which was also reported and discussed in the list not long ago [3]. * Cinterion: Use AT+CFUN=4 or AT+CFUN=7 to go to standby/low-power mode, depending on the supported methods. * Cinterion: Always try to use RTS/CTS flow control in the serial line, so that waking up from standby mode works properly.
