Incase anybody is interested the box looks like one that was being sold by mds , just google PNX84xx-dev_rev_2c.pdf , the pics look identical.
Inside the box near the 2x5 pin header there are 3 pads , pin1 gnd, pin2 tx, pin 3 rx. These are TTL level.
The box boots uboot then the following image:-
Linux version 2.6.34 (root@localhost.localdomain) (gcc version 4.5.2 20101003 (Linaro) [release 4.5-2010.11-1] (Trident STB Cortex Glibc Toolchain) ) #13 SMP Wed Dec 19 19:15:07 HKT 2012
Once the box finishes booting there doesn't appear to be any command line to enter telnet command, just debug output.
