I am just about to start work on my Tonido plugs and I have the TTL Adaptor. I assume the port accesses the SoC console port. I need to know if the TTL Adaptor requires a null-modem cable which I will have to buy or make. It is a pity that the adaptor is not a USB convertor but hey-ho.

Yes it does need a Null Modem cable/adapter. 
It is something we are looking to stock along side/with the TTL Adapter.

Thanks for that. As it happens, I have some old DB9 to RJ45 adaptors on hand and have made a null modem cable with them and a 1 metre Cat 5 cable. Works fine for me. Now to get to work on a kernel more modern than 2.6.31. I note that Kernel 3.6.3 has a topkick machid 4101 so the Tonidoplug kernel may be getting mainlined.

On the backside of the plug there is an serial access port. Lift the rubber piece to allow access to the serial port. This port can be used to gain serial access to the plug computer. This serial access can be used during the Uboot process to modify the boot sequence of the plug.

The port has a 5-pin connector with 4-pins and one missing pin.

x - missing pin
0 - ground
0 - Tx
0 - Rx
0 - Vcc +3.3v
Only three connections are needed:
   ground -> ground
   Tx -> Rx
   Rx -> Tx
