[Elecraft] Solution:Preventing serial port activity during windows boot.

[Tom]

Hi,
While researching using a serial port for DTR handshaking on the K3 I saw a number of posts about the K3 going into transmit when a computer boots up.  Last night, I found a solution, at least for any USB to Serial device that uses the FTDI chipset (which you should use).
If you open the device manager in Windows and double click on the serial port, you can select Port Settings, and then Advanced.  In this page there are two options.  One is “Serial Enumerator” which should Not be checked, and the other is “Disable modem ctrl at startup” which should be checked.
This solves the issue at least for the FTDI chipset.
