The Target Monitoring Tool (TMT) has a ‘Download’ button - but it is unusably slow. 
See: viewtopic.php?f=53&t=1987&p=7399&hilit=tmt+SLOW#p7399
And: viewtopic.php?f=40&t=2428&p=9727&hilit=tmt+SLOW#p9727
That’s because it uses 128-byte XMODEM. 
All it needs is 1K-XMODEM…
In fact, I note that there’s a DownloadXModem.dll in the TMT executable folder - so how about publishing the interface specification, and we can implement whatever custom downloader we like…! 
Since there are so many problems & limitations with the “Target Management perspective” in the new M2MStudio, it really doesn’t yet provide an adequate replacement for TMT - See: viewtopic.php?f=78&t=3500&p=13296&hilit=TMT#p13296
As far as I can see, the only thing missing from TMT as it stands is a usable download facility - and, as noted above, all that’s needed to give that is to update the DLL to use 1K XMODEM (instead of 128-byte XMODEM).
Or if Wavecom would just release the interface specification for the DLL, I’m sure someone (possibly even me) could come up with something…
