# NAME

Device::Modem - Perl extension to talk to AT devices connected via serial port

# WARNING

       This is C<PRE-ALPHA> software, still needs extensive testing and
       support for generic AT commads, so use it at your own risk,
       and without C<ANY> warranty! Have fun.

# SYNOPSIS

      use Device::Modem;

      my $modem = new Device::Modem( port => '/dev/ttyS1', baud => 9600 )

      if( $modem->connect() ) {
          print "connected!\n";
      } else {
          print "sorry, no connection with serial port!\n';
      }

      $modem->attention();          # send `attention' sequence (+++)

      $modem->dial( '022704690' );  # dial number (*NOT WORKING YET*)

      $modem->echo(1);              # enable local echo
      $modem->echo(0);              # disable it

      $modem->offhook();            # Take off hook (ready to dial)
      $modem->hangup();             # returns modem answer
      $modem->reset();              # hangup + attention + restore setting 0 (Z0)

      $modem->restore_factory_settings();
                                    # Handle with care!

      $modem->send_init_string();   # Send initialization string
                                    # Now this is fixed to `ATZ0H0V1Q0E0'

      $modem->repeat();             # Repeat last command

      $modem->verbose(0);           # Modem responses are numerical
      $modem->verbose(1);           # Normal text responses

      #
      # Some raw at commands
      #
      $modem->atsend( 'ATH0' );
      print $modem->answer();

      $modem->atsend( 'ATDT01234567' . Device::Modem::CR );
      print $modem->answer();

# DESCRIPTION

Device::Modem class implements basic AT device abstraction. It is meant to be inherited by sub classes (as Device::Gsm), which are based on serial connections.

## REQUIRES

Device::SerialPort

## EXPORT

None

# TO-DO

- AutoScan

  An AT command script with all interesting commands is run when `autoscan' is invoked, creating a `profile' of the current device, with list of supported commands, and database of brand/model-specific commands

- Time::HiRes

  Check if Time::HiRes module is installed and use it to wait milliseconds instead of whole seconds

- Many more to come!
