P.S. It appears python also has encoders and decoders:
https://docs.python.org/2/library/base64.html
using:
>>> import base64
>>> encoded = base64.b64encode(‘data to be encoded’)
>>> encoded
‘ZGF0YSB0byBiZSBlbmNvZGVk’
>>> data = base64.b64decode(encoded)
>>> data
‘data to be encoded’

/dev/ttyXRUSB0 is new to me. Any reference links on how serial USB works? Also, since I have your attention: would you have a link on how to interpret “data”:”aGVsbG8gd29ybGQ=” as “hello world”? Is it just a matter of converting from ascii to hex and then reversing bytes? Finally, any thoughts on why the re-flashing timed out when I dropped
mDot_AT_firmware_XDOT_L151CC.bin onto the maintenance window? Finally,finally, if MultiTech had a site of categorized gotchas and fixes, I would be a willing contributor. Thanks again for getting me back up and running; appreciated.
