I doubt it is easy to know what a Windows binary-only application might
be sending over the wire. It is easy to build a sniffer with a computer
in the middle though.
But if the flow control is a possible issue, then maybe the bm driver
can be hacked so each byte is sent one by one with a 10 ms delay between
them just to validate this hypothesis. Preferably over the serial port
to have the least number of intermediate layers.
