Hi James,
I think you choose the firmware versions based on your idea and meanwhile mix the firmware written for the 2.8 "and 4" (3.95 ") versions. Yet these should not be confused with each other because they use a different microprocessor. They will not work with the firmware written for the other.
For example, you are writing here:
/g/nanovna-users/message/20975 -H4 you are experimenting with firmware. Do not do it.
You may not allow the other to charge immediately.
Managing terminal programs For PuTTY, the Port, Speed ??and Serial markings must be set in the Configuration. You can find their information in PC Device Manager when you connect to your device.
All three data must match for PC and PuTTY.
I assume that the driver is already on the PC, so if the connection is successful, it is advisable to type the word 'help' when the cursor is flashing, because in response you will see the possible commands.
In the wiki or files folder you will find a list of possible consol commands and what commands they accept.
You can also find more on the website of the creator of the given program.
