XMODEM protocol implementation

Documentation available at http://packages.python.org/xmodem/

Python Package Index (PyPI) page is available at https://pypi.python.org/pypi/xmodem

Usage

Create a function to get and put character data (to a serial line for example):

>>> from xmodem import XMODEM
>>> def getc(size, timeout=1):
...     return data or None
...
>>> def putc(data, timeout=1):
...     return size or None
...
>>> modem = XMODEM(getc, putc)

Now, to upload a file, use the send method:

>>> stream = open('/etc/fstab', 'rb')
>>> modem.send(stream)

To download a file, use the recv method:

>>> stream = open('output', 'wb')
>>> modem.recv(stream)

For more information, take a look at the documentation.
