I don't know anything about that specific setup, nor anaything aabout your 
personal expertise.

When you say "nothing on 232", is thatr per looking at the wires of the 
cable?  Or just not getting anything displayed by Putty?

When you say "knitted appropriately", since that is NOT referring to "as 
per the manual" (or is it?), have you checked all inputs and outputs?
Sometimes devices, at either end of the cable, have unexpected 
requirements,that are not usual parts of the RS232 "standard".

For example, I was once asked by the "Radio Shack Computer Center" to help 
them connect a Votrax to a Model 2 (for a blind customer).  They had tried 
all of the obvious commodity "null modems", etc.  I used a "matrix 
switch", but also had to solder one additional jumper for a pin that is 
not "normally" used for such things, and no obvious reason for being used. 
I no longer remember which pin; it was possibly #10 or #12, but it might 
just have been #22 ("ring indicator").  To avoid the bureaucratic 
administrative nonsense needed for them to pay me, I accepted a gift of a 
Model 2 Technical Reference manual as compensation.
