[NTLK] OMP serial connection problems

Cracked the unit open this morning to try and remedy what I though was a
flux issue on the board near the serial port. Surprisingly, I may have done
this a few years ago. What was really shocking though was the residue left
behind. I had used 70% alcohol back then - not 91% or higher. Cleaned that
up. Hoping it did not leave damage behind. It looks "okay" to the naked
Still no go on the serial though.
Tried to use the HyperTerminal program in VirtualPC. No data coming though.
I haven't used it before though, but I opened up the COMM port to
communicate. Did not see anything. Any advice on using that program?
Also downloaded another COMM monitoring software for Windows Vista. No
action detected. Again, never used this stuff before.
Looks like I talked about this issue on year way way back three years ago.
That of course was with a different machine, OS, USB serial adapter - oh
yes, and I ACTUALLY worked. When I get the chance in a few weeks, I'll give
the older hardware a go and see if it makes a difference.
Any input is appreciated. Thanks
