Had some luck.
Figured i may as well dig an old computer out of the attic which happened to have a serial port and xp installed. Same issues again so i made up a fresh RS232 cable just to make sure that wasn't the problem and now thankfully I am getting some life out of it.
Update
All back up and running, seems there was a problem with the cable.
Thanks for the help Fairbird, much appreciated.
