[Elecraft] question on old topic K3 Key-down on power-up [Solution?]"

[Lee Hill]

Hi:

I recently purchased a used K3.

I have noticed the exact problem described in posts in 2008,
http://marc.info/?l=elecraft&m=121462133723056&w=2

where the K3 goes into transmit due to a connected computer's serial port
-  when the computer first powers up and the serial port has not yet been
configured by a logging or serial control program.

The undesired behavior stems from the K3 PTT being asserted by the computer
at the rig's serial port via DTR or RTS (depending on the K3 setup) The
problem goes away after the logging or serial port control program is
launched.

Was a feature discussed in the above post implemented in later firmware?
 The feature is the rig detects an asserted PTT during the first couple of
seconds of power up and goes into TX test mode and/or displays and error.

I haven't done any HW or firmware upgrades to the rig yet.

thank you
