[Elecraft] K3 - COM port iterating ...

[Thomas Norff]

Hi Nick,

that's quite normal. All interfaces (each USB-Port is one interface !) are
enumerated during the boot process of your OS.
Each USB-Port will stay the same COMn after reboot. Connecting the converter
to a different USB-Port is the same as connecting a new converter to the
system.

Maybe there is a way to manually modify the enumeration after reboot.
I would prefer to just remember which USB-Port i used the last time.

Subject: [Elecraft] K3 - COM port iterating ...

I use the USB to serial converter from Elecraft to connect my laptop to my
K3.  When I initially plugged it in it configured itself as COM 4.  
Hmmm?  My laptop doesn't have any real serial ports. 

Later, I moved it to a different connector and lost communications.  The COM
port had re-configured itself as COM 5.  So I changed the settings on my
software to suit and things were good.  I wondered if this behavior was
somehow related to the specific USB port.  So I moved the connector back to
the initial USB port.  This time the COM port iterated up to COM 6. 

I wonder if there's a way to tell this thing to be the same COM port each
time I plug it in?  My computer is a fairly new Dell laptop running Vista.
As recommended, I let Vista go out and find the best driver for it on the
web.
