Well after hours and hours of non stop research and testing I have found out that my seemingly unidentifiable UPS, which was purchased so cheaply, is still unidentifiable, BUT I have worked out it makes use of the Fenton UPS Protocol, or Megatec/RUPS2 Protocol...or some sort of clone of that Protocol.
After playing around with serial line monitors, and terminal programs I discovered that the UPS is using a Megatec/RUPS like protocol, but it doesn't appear to be completely compatible...well not with the version of Megatec Protocol I was using as a reference. The Official Megatec protocol specs can be found at: http://www.exploits.org/nut/library/protocols/megatec.html When I issued commands to the UPS my self by hand using a terminal program I was only able to get 4 of them to work...well only 4 had a visible or audible result.
