XMODEM Module for Python

[jfhamilt at usgs.gov]

Hi.

I am wiriting a program that retrieves and manipulates data from a variety 
of sensor / data recorder hardware.  One of these types of equipment 
requires the use of XMODEM to transfer the data file.  I'd like to avoid 
having to write my own XMODEM code, so I was wondering if anyone knew if 
there was a python XMODEM module available anywhere?

Thanks.
