Thanks Tom - I also got the following from Bob, N6TV, concurring with your
post and adding a bit more about Windows 10 FTDI Settings.

Hi Dana and Kevin,
This is a Writelog issue, and can be fixed. But first make sure that the
FTDI Device Driver options for both K4 COM ports are set to "Disable Modem
Control at Startup" and that "Serial Enumeration" is disabled. The Windows
defaults (which can get reset after a Windows 10 update, as they did
recently), are not good. See slide 27 and following in this presentation:
- Everything You Need to Know About USB and Serial Interfaces
<https://bit.ly/USBserial2021>, updated for 2021
Here's what W0YK found some time ago:
I found the following in the WL Help file:
*The COMn_RTS_INIT and COMn_DTR_INIT settings are for the ports used for
rig control (only--not FSK or any other COM port uses) and change the
way WriteLog initializes the RTS and DTR lines **on** the rig port. Setting
the value to 0 (zero) causes WriteLog to initialize the line off. Setting
the value to 1 (one) causes WriteLog to initialize the line **on*
* (which is the default if there is no entry). Setting the value to
anything else, like -1 (minus one), causes WriteLog to not change the
port.WriteLog supports RTS/CTS flow control for some rig drivers that turn
that feature **on**, but only if you also set COMn_RTS_INIT = -2*
COM1_RTS_INIT=-2
COM1_DTR_INIT=1
Adding these two statements to writelog.ini solved that problem:
COM1_RTS_INIT=0
COM1_DTR_INIT=0
Where you would substitute the COM port number, so for COM5:) set both
COM5_RTS_INIT and COM5_DTR_INIT to 0 in writelog.ini.
