# Device::Modem::UsRobotics(3pm)

USR modems extensions to control self-mode

## NAME

Device::Modem::UsRobotics - USR modems extensions to control self-mode

## SYNOPSIS

```
  use Device::Modem::UsRobotics;
  my $modem = Device::Modem::UsRobotics->new( port => '/dev/ttyS1' );
  $modem->connect( baudrate => 9600 );
  my %info = $modem->messages_info();
  print "There are $info{unreleased_voice_msg} unread voice messages on $info{stored_voice_msg} total\n";
  print "There are $info{unreleased_fax_msg} unread fax messages on $info{stored_fax_msg} total\n";
  # Get details about message n. X
  my %msg = $modem->message_info(1);
        index type information attributes status day hour minute
        callerid page addresshigh addresslow checksum
  print 'This is a ', ($msg{type} == 2 ? 'voice' : 'fax'), 'message', "\n";
  print 'It came from no. ', $msg{callerid}, "\n";
  # ...
  # Now clear all messages
  $modem->clear_memory();
```

## WARNING

This module is not documented yet, and it is a rough work in progress. Until now, it correctly reads voice/fax messages information, but when saving voice messages to disk, sometimes they are incorrectly decoded.

So, if you need a working program, check out the good old TkUsr by Ludovic Drolez, unless you want to help develop Device::Modem::UsRobotics.

## DOCS TO BE COMPLETED FROM NOW.....

Yes, I'm a bad boy :-)

## DESCRIPTION

Bla Bla Bla...

## METHODS

### clear\_memory()

Used to permanently clear the memory space of the modem. There are separate memory spaces, one for voice/fax messages and one for user settings. Examples:

```
        $modem->clear_memory('user');     # or $modem->clear_memory(1)
    $modem->clear_memory('messages'); # or $modem->clear_memory(2)
```

To clear both, you can use:

```
    $modem->clear_memory('all');      # or $modem->clear_memory(0);
```

Parameters:

- $memtype

  String or integer that selects the type of memory to be cleared, where `0` is for `"all"`, `1` is for `"user"` memory, `2` is for `"messages"` memory.
