#77 File send bug with some Windows10 PC and 2.0.0.70 and 3.0.0.30

[Bruce Boyes]

On multiple PCs running Win10 and Win7, we have a file send problem. It's a text file used to send configuration data to an embedded system. To give our embedded system time to write a line of config data to FRAM via I2C we set line delay to 100 msec.
Windows 7 Pro 64, RT 2.0.0.70 always works.
Win 10 and 7, RT 3.0.0.30 never works.
Win 10 and RT 2.0.0.70 some systems work and some don't. Two Win 10 Pro 64 systems file send works. One Win10 Home 64 works! How odd is that?
Lines in the file look like this:

#lights on/off times in hh:mm (24hr clock)
lights on = 7:00
lights off = 19:00

I'm gathering more data (instead of writing code... that's how this week has gone) and will update here with any findings.

Is it repeatable on one system?
Is handshaking on or off?
Is it related to the usb-serial convertor?
