EDIT,

Nevermind got out my trusty FTDI and got it working myself,
RX on FTDI to pin 7 on EXP
TX on FTDI to pin 8 on EXP
Gnd on FTDI to pin 6 on EXP

Set for 115200 8n1 and works great.

Glad to know it works now. Using the UART0 at EXP port is better than UART 0 at Euler port for console connection, this due to EXP port one has voltage shifter circuit.

My PINE hasn't arrived yet (ETA is end of MAY). I however have Raspbery 1 B+ and ordered USB to RS232 TTL from here http://www.ebay.co.uk/itm/310676792112?_...EBIDX%3AIT .

It is based on Prolific pl2303hx chip.
There are four wires and is connected to PI bus:
red power, (do not conected to raspberry!)
black ground, (pin6)
white RX into USB port, (pin8)
green TX out of the USB port. (pin10)

I had to use this driver (http://www.adafruit.com/datasheets/PL2303%201.0.13.zip)  on my Win 7 computer and it worked well. Tested for about 30min.
I should therefore work on PINE as well. But as Tllim said safer should be to use EXP bus rather.
