Hello Neville and all the others starting with Thunderbolt,
TBoltMon is very helpful, but some functions are difficult to find.
In case the com parameters are unknown or changing due to (MS)-OS
Execute TBoltMon, select in 'ser. port window' com1 (default) and hit 'ok'.
In the following main window of the program klick with the right mouse
key somewhere in that main window, select in the appearing menu
'auto find all', the program will find all the existing com ports and the
active port with Thunderbolt for you, passing along with the cusor to the
fields, you will find in the bottom line further explanations and instructions,
right clicking does sometimes open further menus.
Select the active port with the green marker aside (TBolt activities found)
with a mouse click.
Have fun with it,
