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):

>>> 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)

For more information, take a look at the?documentation.
