-How to configure modem support in U-Boot :
-
-1. Define modem initialization strings:
----------------------------------------
-
-The modem initialization strings have following format:
-
- mdm_init1=<AT-command>
- mdm_init2=<AT-command>
- ...
-
-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/<board>.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. RTS/CTS flow control is enabled for the serial port.
-(The RTS/CTS flow control is enabled by default on the modem).
-
-
-SAMSUNG # setenv mdm_init1 ATZ
-SAMSUNG # setenv mdm_init2 ATS39=0+IFC=0,0 - disable modem
- RTS/CTS flow control
-SAMSUNG # setenv mdm_init3 ATDT1643973 - dial out the number
-SAMSUNG # setenv mdm_flow_control none
-SAMSUNG # saveenv
-
-The example above initializes modem to dial-up connection on the
-number 1643973. Flow control is disabled.
-
-Note that flow control must be turned both off or both on for the
-board serial port and for the modem.
-
-
-If the connection was set up successfully, the U-Boot prompt appears
-on the terminal console. 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. For the
-Rockwell OEM modem this can to be done with the following command:
-
-AT&D0&W
