NAME

       Device::Gsm::Pdu - library to manage PDU encoded data for GSM messaging

WARNING

	  This is C<BETA> software, still needs extensive testing and
	  support for custom GSM commands, so use it at your own risk,
	  and without C<ANY> warranty! Have fun.

NOTICE

	   This module is meant to be used internally by C<Device::Gsm> class,
	   so you probably do not want to use it directly.

SYNOPSIS

	 use Device::Gsm::Pdu;

	 # DA is destination address
	 $DA = Device::Gsm::Pdu::encode_address('+39347101010');
	 $number = Device::Gsm::Pdu::decode_address( $DA );

	 # Encode 7 bit text to send messages
	 $text = Device::Gsm::Pdu::encode_text7('hello');

DESCRIPTION

       "Device::Gsm::Pdu" module includes a few basic functions to deal with SMS in PDU mode, such as encoding GSM addresses (phone numbers) and,
       for now only, 7 bit text.

FUNCTIONS

   decode_address( pdu_encoded_address )
       Takes a PDU encoded address and decodes into human-readable mobile number.  If number type is international, result will be prepended with
       a `+' sign.

       Clearly, it is intended as an internal function.

       Example

	   print Device::Gsm::Pdu::decode_address( '0B919343171010F0' );
	   # prints `+39347101010';

   encode_address( mobile_number )
       Takes a mobile number and encodes it as DA (destination address).  If it begins with a `+', as in `+39328101010', it is treated as an
       international number.

       Example

	   print Device::Gsm::Pdu::encode_address( '+39347101010' );
	   # prints `0B919343171010F0'

   encode_text7( text_string )
       Encodes some text ASCII string in 7 bits PDU format, including a header byte which tells the length is septets. This is the only 100%
       supported mode to encode text.

       Example

	   print Device::Gsm::Pdu::encode_text7( 'hellohello' );
	   # prints `0AE832...'

   pdu_to_latin1($pdu)
       Converts a PDU (without the initial length octet) into a latin1 string.

       Example

	   my $pdu = 'CAFA9C0E0ABBDF7474590E8296E56C103A3C5E97E5';
	   print Device::Gsm::Pdu::pdu_to_latin1($pdu);
	   # prints `Just another Perl hacker'

   latin1_to_pdu($text)
       Converts a text string in latin1 encoding (ISO-8859-1) into a PDU string.

       Example

	   my $text = "Just another Perl hacker";
	   print Device::Gsm::Pdu::latin1_to_pdu($text);
	   # prints `CAFA9C0E0ABBDF7474590E8296E56C103A3C5E97E5'
