Define modem initialization strings: ---------------------------------------- - -The modem initialization strings have following format: - - mdm_init1= - mdm_init2= - ... - -Turning off modem verbose responses with ATV0 or ATQ1 is not allowed; -U-Boot analyzes only verbose (not numeric) result codes. Modem local -command echo can be turned off (ATE0). - -2. RTS/CTS hardware flow control: ---------------------------------- - -You may wish to enable RTS/CTS hardware flow control, if the board's -UART driver supports it (see CONFIG_HWFLOW compile-time flag in -config/.h). This is controlled by the 'mdm_flow_control' -environment variable: - - 'mdm_flow_control=rts/cts' - to enable RTS/CTS flow control. - 'mdm_flow_control=none ' - to disable. - - -The following are the examples using a Rockwell OEM modem -configuration: - -SAMSUNG # setenv mdm_init1 ATZ - reset the modem to - the factory defaults. -SAMSUNG # setenv mdm_init2 ATS0=1 - set modem into - answer mode. -SAMSUNG # setenv mdm_flow_control rts/cts - enable serial port - flow control -SAMSUNG # saveenv - -The example above initializes modem into answer mode to wait for the -incoming call.

If not (U-Boot modem was configured for -originating the call and connection was not established) - the board -should be reset for another dial-up try. - - -Note on the SMDK2400 board: ---------------------------- - -Since the board serial ports does not have DTR signal wired, modem -should be told to ignore port DTR setting prior to connection to the -SMDK board, and this setting should be stored in modem NVRAM.
