[WriteLog] Erratic Keying

[marsh at ka5m.net]

I have a problem with erratic keying.

My setup:
Dell Computer with an i5 Quad Core 3.1 MHz
Windows 10 Pro 64-bit
WriteLog v 12.55G
Icom-7851

The Icom-7851 has the latest firmware version 1.31.
For radio to computer communication, I'm using a single USB cable, Icom USB
Driver and USB Audio CODEC version 1.30.
The USB Driver set up 2 virtual COM ports, COM5 and COM6. COM5 is used for
rig control and CW keying on DTR. COM6 handles PTT for FT8, and PTT and
keying for RTTY.

For contesting I press the [F2} key to send my exchange - for the Mini-CWT
Sessions it is MARSH 1433. From 1 to 4 out of 10 [[F2] presses gibberish is
sent.

Any suggestions or comments would be appreciated.
