[Elecraft] N1MM

Hello Bob. I'm also using a wireless connection with a card in my old IBM
380ED and like yours, it works quite well.  You didn't say what version of
Logger  you were using but I'm guessing that as far as parallel port keying
goes that it does not (or at least should not) make any difference.  You
must be using XP or 2000 since you said that you installed the "port"
program.

The only thing I can come up with would be to make sure the "Other" block is
checked in the Logger set-up  - just opposite the LPT port that you have
selected - AND - that the proper CW/Ptt Port Address is entered in the
window.  I recall reading that for some systems the Logger default value for
the port address is not correct.  You should be able to look at your
hardware set-up on the computer to see what the address is for the LPT port
that you are trying to use and then enter that value in the window.

 Next, I would remove the laptop from the port replicator and then use a
vom/dmm to check for keying action right at the parallel port on the
computer (usually pin 17) to verify (or not verify) changes in the state of
the port output.  This would eliminate any problems that might be inherent
in the port replicator or the keying interface you are using.

I'm probably way out on the limb here (gulp) but I'm guessing that it will
turn out to be either the "Other" check or that the selected LPT port
address is not correct.

Try a post on the N1MM group reflector.  I'll bet the group will come up
with a number of other ideas.

Sure hope you get this solved.  It can become intensely frustrating quickly!
With the K2 really gaining popularity for contesting finding solutions to
these problems is of interest to lots of us.  73  --don n4hh
