[Elecraft] FW: FTDI to serial adapter for K3 with Windows 7 change. Why?

[Dick Dievendorff]

During OS startup and device driver initialization the rs-232 control lines
(DTR and or RTS) are sometimes wiggled. If your K3 is configured to PTT or
KEY on these RS-232 signals, it can transmit.  Check k3 config PTT-KEY.

This happened to me a lot when I used this keying technique with N1MM.

Something has changed but it isn't the FTDI driver. The command is coming
from the Win 7 OS generating it with the FTDI driver.  Is there something in
the BIOS that has changed?  This is the Elecraft FTDI chip set cable.
