Folco (./78) :
A Directory Listing or a requesting of a variable. Probably a directory listing of the Home directory due to the size (and PedroM answer of 0x20 bytes = 4 null first bytes + 2*14 bytes for each folder - main and system). I don't see anything wrong in it.
Directory listing, Ti-Connect just displays the list of the directories (indeed, I had just main & system).
The calc browsing seems to work fine. This is the device and system detection which fails (first log I gave to you).
So receiving / sending files work?
