Show version routine. Again a user operation via a different machine. The User sets a byte sequence using a button combo on a Roland mixer. It sends the bytes to the DIF-AT, and it responds by printing the DIF-AT Version number over midi, on the mixer display screen.

These operations are described below. I found them on Roland's site, and then looked for the relevant part of the firmware which checks for these bytes. Notes from examining the firmware - '''''Send single byte 0x06 from host to device. That causes the device to: enter Show-Version handler run fcn.ShowVersionSequence() transmit the version bytes to host. return to idle mode'''''
