Help on class GsmModem in module pygsm.gsmmodem:

class GsmModem(__builtin__.object)
 |  
 |  pyGSM is a Python module which uses pySerial to provide a nifty
 |  interface to send and receive SMS via a GSM Modem. It was ported
 |  from RubyGSM, and provides (almost) all of the same features. It's
 |  easy to get started:
 |  
 |     # create a GsmModem object:
 |     >>> import pygsm
 |     >>> modem = pygsm.GsmModem(port="/dev/ttyUSB0")
 |  
 |     # harass Evan over SMS:
 |     # (try to do this before 11AM)
 |     >>> modem.send_sms("+13364130840", "Hey, wake up!")
 |  
 |     # check for incoming SMS:
 |     >>> print modem.next_message()
 |     <pygsm.IncomingMessage from +13364130840: "Leave me alone!">
 |  
 |  
 |  There are various ways of polling for incoming messages -- a choice
 |  which has been deliberately left to the application author (unlike
 |  RubyGSM). Execute `python -m pygsm.gsmmodem` to run this example:
 |  
 |     # connect to the modem
 |     modem = pygsm.GsmModem(port=sys.argv[1])
 |        
 |     # check for new messages every two
 |     # seconds for the rest of forever
 |     while True:
 |         msg = modem.next_message()
 |         
 |         # we got a message! respond with
 |         # something useless, as an example
 |         if msg is not None:
 |             msg.respond("Thanks for those %d characters!" %
 |                 len(msg.text))
 |         
 |         # no messages? wait a couple
 |         # of seconds and try again
 |         else: time.sleep(2)

 |  Methods defined here:
 |  
 |  __init__(self, *args, **kwargs)
 |      Creates, connects to, and boots a GSM Modem. All of the arguments
 |      are optional (although "port=" should almost always be provided),
 |      and passed along to serial.Serial.__init__ verbatim. For all of
 |      the possible configration options, see:
 |      
 |      http://pyserial.wiki.sourceforge.net/pySerial#tocpySerial10
 |  
 |  boot(self, reboot=False)
 |      Initializes the modem. Must be called after init and connect,
 |      but before doing anything that expects the modem to be ready.
 |  
 |  command(self, cmd, read_term=None, read_timeout=None, write_term='\r')
 |      Issue a single AT command to the modem, and return the sanitized
 |      response. Sanitization removes status notifications, command echo,
 |      and incoming messages, (hopefully) leaving only the actual response
 |      from the command.
 |  
 |  connect(self, reconnect=False)
 |      Creates the connection to the modem via pySerial, optionally
 |      killing and re-creating any existing connection.
 |  
 |  disconnect(self)
 |      Disconnects from the modem.
 |  
 |  hardware(self)
 |      Returns a dict of containing information about the physical
 |      modem. The contents of each value are entirely manufacturer
 |      dependant, and vary wildly between devices.
 |  
 |  next_message(self, fetch=True)
 |      Returns the next waiting IncomingMessage object, or None if
 |      the queue is empty. The optional _fetch_ parameter controls
 |      whether the modem is polled before checking, which can be
 |      disabled in case you're polling in a separate thread.
 |  
 |  ping(self)
 |      Sends the "AT" command to the device, and returns true
 |      if it is acknowledged. Since incoming notifications and
 |      messages are intercepted automatically, this is a good
 |      way to poll for new messages without using a worker
 |      thread like RubyGSM.
 |  
 |  query(self, cmd)
 |      Issues a single AT command to the modem, and returns the relevant
 |      part of the response. This only works for commands that return a
 |      single line followed by "OK", but conveniently, this covers almost
 |      all AT commands that I've ever needed to use.
 |      
 |      For all other commands, returns None.
 |  
 |  send_sms(self, recipient, text)
 |      Sends an SMS to _recipient_ containing _text_. Some networks
 |      will automatically chunk long messages into multiple parts,
 |      and reassembled them upon delivery, but some will silently
 |      drop them. At the moment, pyGSM does nothing to avoid this,
 |      so try to keep _text_ under 160 characters.
 |  
 |  signal_strength(self)
 |      Returns an integer between 1 and 99, representing the current
 |      signal strength of the GSM network, False if we don't know, or
 |      None if the modem can't report it.
 |  
 |  wait_for_network(self)
 |      Blocks until the signal strength indicates that the
 |      device is active on the GSM network. It's a good idea
 |      to call this before trying to send or receive anything.
