A bunch of questions / doubts ...I ordered this v2 unit [1] (N5105/no ram/no storage)on August 6th and it was delivered on the 15th to Germany without additional taxes/fees. They currently have a discount of 2EUR for every 25EUR spent, so only 157EUR for the plain N5105 unit.
So far this unit seems nicely built. I removed the huge amount of thermal compound and only left a decent amount on the 2 DIEs. They sit perfectly on the aluminium spacer with a slight pressure due to the fact that the mounting studs are a bit shorter than the spacer. Case gets warm/hot'ish' but not too bad for a passively cooled unit (some PoE switches get way hotter), CPU temp sits at ~55° and max I saw was 71° when switching to the BIOS direcly after the kernel relinking at the end of the OpenBSD setup. There were lower temps posted here, but this thing has a Tjmax of 105° so I couldn't care less about those temperatures...
I'm only having one problem:
Is anyone using the serial port on one of these boards? I can get the console output, but no inputs are recognized by the unit; neither at POST/BIOS, nor by the booted OS (OpenBSD). So I currently have to connect a USB keyboard to the unit...
I'm connecting via screen using a USB/Serial adapter and Cisco serial cable; both are working perfectly fine with other equipment (cisco and non-cisco /w rj45 serial), so I don't think the cables are the problem but the BIOS settings.
Im currently using those default settings:

(Terminal Type VT100+ gives me colors, but in BIOS the selected item is the same color as the background, so I switched back to VT100 for the screenshots)
Already tried enabling "recorder mode" (disabled should be right, but wouldn't be the first BIOS with inverted/wrong logic on some options...), various options of the "putty keypad" option (no clue what putty has to do with the console redirection...) and various non-standard combinations of data/parity/stop bits and flow control, but it seems this thing just completely ignores any input via serial console. Even OpenBSD with console on com0 doesn't get any input, so it has to be the firmware that discards it.
(yes, the cable/adapters are working. I'm using them nearly every week and I just double-checked by connecting to the com-ports on some cisco and juniper gear here)

- Is the console port a RS232 ( 12V ) or a TTL ( 5V ) console ? I have a bluetech mobo that include a console port but that are no specs.
- In the settings of the terminal you try using "flow control none" ? not in bios but in the terminal emulator .
Putty is a terminal emulator ( ansi, vt100, vv220 etc ) that includes serial, telnet and ssh connections.
