[nmglug] [dt-general] USB port string

[a]

Marc:
My adapter is usb to serial.
The three tricks I have know,did the trick and Digitemp is reading the
one sensor I have installed.
I will likely head your advice and Brians and stick with the serial to
serial adapter i.e. as soon as I get that worked out.
Anyway you made my day a bit sunnier.much thanks, Anthony K
