Hi,i tried using teraterm on my vna,it connected ok using com 19,i ran learconfig 1234,now it wont connect to my pc,terraterm only sees com 1 not 10,the stm32 bootloader tab in device manager says cant find driver,i assume this is my issue,its like my win 10 64bit pc cant see my nanovna anymore,any ideas how i can fix it?,or where to find the drivers?,cheers+73.
