Usage

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

>>> import serial
>>> from xmodem import XMODEM
>>> ser = serial.Serial('/dev/ttyUSB0', timeout=0) # or whatever port you need
>>> def getc(size, timeout=1):
...     return ser.read(size) or None
...
>>> def putc(data, timeout=1):
...     return ser.write(data)  # note that this ignores the timeout
...
>>> 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)
