Question about USB Serial Adapter

I am having some trouble with the Nanostation M2.  I decided to try the Unbricked procedure from Ryan Elliot - AI6NE.  I purchased a Gearmo  FTDI-LED RS-232 USB 2.0 Serial Adapter.  I think it is installed OK.  I have the M2 apart and connected to pins 2,3 and 5 on the adapter per the instructions.  I have been trying to use PUTTY.  I configure the Putty as serial mode using the parameters in the instructions.  I can get a console up, but it does not seem to be communicating with the M2.  Does anyone have any suggestions to help move me along further?  Is there a better console software to use?  I have telnet in windows, but it does not seem to have configuration options.
Thanks
