What I want to do is to use an embedded system serial port login for maintenence access, see the bootup log which remote system puts onto db9 serial port, later gives a login prompt that I would like to login to and then be able to check on the system, initiate reboot if needed, collect data, install new files etc.

I have two different db9 serial-bluetooth adapters now, and neither accomplish this as far as I can tell. I have done aloopback test on one of them, which passes, but it cannot talk to a usb-serial adaptor, even with nullmodem adapter in between the two db9 ends. For every byte I type into the bluetooth side RealTerm, I get 3 bytes out at the USB end, like the two db9 ports are talkign different languages, but htey are all configured to baud, 8N1, no hardware handshake, so no reason to be different.

Believing my first buetooth-serial adapter to be garbage, I bought another from adifferent brand, with different shape, internal antenna vs big bendy antenna etc. But sedond one behaves much like the first, and so I assume now that perhaps the concept is wrong for bluetooth? Or perhaps that Windows10 is flaky in this regard, as I find a lot of other complaints about Bluetooth COM ports in Win10, when their thigns had worked fine in Win7, Win8.

By USB-serial adapter connects just fine to my embedded platform and shows me the boot log, lets me login etc. I want that same thing over bluetooth, rather than having a very long serial wire going down the hallway between rooms Or make some other suggestion of a nice db9 serial-something else adapter isntead of bluetooth.
