[NTLK] OMP serial connection problems

[Tony Kan]

Just a suggestion:  You may need to get the multitester out and check if there is any voltage going through to the serial port at all.  Sorry can't walk you through it as I've never done it myself.  Frank Gruendel is our resident hardware guru, he might be able to.

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 eye.

Still no go on the serial though.
