Yep, there was a driver loaded in there I forgot about.  I have an external
R/W CD ROM Drive I use for back up, etc.  It uses the parallel port. I
disabled it and everything is working fine now.

Thanks to everyone who responded.  I should know better than to work on
this stuff at 3:00 AM, let alone post stuff at that time. At least I'm not
getting it ready at 3:00AM *the night before* CQWW! :-)

Thanks & 73 - Gary, W9XT

I know you're a very astute engineering type, so I'm sorry if you
already checked this stuff... 

I have seen Windows do this with certain items installed.  I had a
scanner that did this.  I guess it would also be possible for certain
printers. Since Windows collects status from the printer now by
communicating instead of just thru the usual handshake pins.

I have also had this kind of problem with the serial port (I know you
said LPT) with the Palm Pilot software loaded... it keeps pinging the

Before you disable the port, maybe try selecting a different default
printer?  Wonder what printer it is?

I run NA on a Win98 machine in a window and have no problems like this. 
I use the LPT port for 2-radio control and cw/ptt...etc (soon for your
external DVK).  Actually I do it on multiple machines, desktop and
notebook.  I suspect it is something you have loaded that keeps pinging
the port.

BTW, whenever you are ready to start testing those external DVK's... I
would be happy to test one... and of course buy one.
