Okay! I got the patched tarball, unpacked it, ran configure and make then make 
install. No probs!

I tested the update driver and the result was still a validation error!
This is the console debug output!

gatekeeper nut #  /lib/nut/powercom -a APC1 -DDDDDDDDDDNetwork UPS Tools - 
PowerCom protocol UPS driver 0.13 (2.6.0-r2984)
   0.000000     debug level is '10'
   0.002388     Flow control disable
   0.002561     Num of bytes requested for reading from UPS: 16
   0.148057     Num of bytes received from UPS: 16
Raw data from UPS:
 0 0x10 ( )
 1 0x64 (d)
 2 0x68 (h)
 3 0x68 (h)
 4 0x32 (2)
 5 0xff (ÿ)
 6 0x32 (2)
 7 0x00 ( )
 8 0x00 ( )
 9 0x04 ( )
10 0x00 ( )
11 0x4b (K)
12 0x98 ()
13 0x00 ( )
14 0x00 ( )
15 0x00 ( )
   0.148222     data receiving error (validation check)


So there you have it! No phix yet! My C knowledge is not at a higher enough 
level to tackle on my own! I learnt just enough to get the feel of it! Just 
like cobol, algol and other weird languages!

I can see the bit were the validation happens but I cannot get my head around 
it! Seems it checks each byte in turn but then I'm lost! I really wish I could 
hep a bit more!

Cheers
Ang
