Universal communication interface using File-Like API

Project description

Pylink offers a universal communication interface using File-Like API. For now, only the TCP, UDP, Serial and GSM interfaces are supported.

The aim of this project is to allow any type of communication. It is best suited for projects that have various ways of communicating including IP remote or local serial communication.


You can install, upgrade, uninstall pylink with these commands:

$ pip install pylink
$ pip install --upgrade pylink
$ pip uninstall pylink

Or if you don’t have pip:

$ easy_install pylink


>>> from pylink import TCPLink, link_from_url
>>> link = TCPLink('localhost', 7) # conntect to echo tcp service
>>> link.write('Hello')
2012-06-05 12:44:06,211 INFO: new <TCPLink tcp:> was initialized
2012-06-05 12:44:06,211 INFO: Write : <b'hello'>
>>> == 'Hello'
2012-06-05 12:44:06,312 INFO: Read : <'hello'>

With GSMLink, you shoud specify the modem connection link:

>>> from pylink import GSMLink, SerialLink
>>> link = GSMLink("0678986955", SerialLink("/dev/ttyUSB0", 38400))
2012-06-29 15:13:31,637 INFO: new <SerialLink serial:/dev/ttyUSB0:38400:8N1> was initialized
2012-06-29 15:13:31,637 INFO: GSM : Call 0678986955
2012-06-29 15:13:31,638 INFO: Write : <u'ATD0678986955\r\n'>
2012-06-29 15:13:31,648 INFO: GSM : <u'call in progress'>

>>> link.write("TEST\n")
2012-06-29 15:14:16,193 INFO: Write : <u'TEST\n'>
2012-06-29 15:14:24,972 INFO: Read : <u'\n\rTEST\n\r'>


>>> link.close()
