[WriteLog] Problem with erratic cw

1. RFI can cause some keying problems; did you try without an amp?
2. I recall some reports of problems with USB to Serial
for certain manufacturers, that they were too slow for
either rig control or CW sending, but have no specific
reference for you.
3. I used Belkin F5U103 USB to Serial with Dell Inspiron,
WIN/XP Pro in WPX this weekend, and had no erratic keying,
Twice, after hitting an unknown combination of keys
(the second time, I think it was ESC and the
Squiggle Character keys, maybe)
I got blue screen with BUG_CODE_DRIVER error that
4. I had started out WPX using internal COM1 for CW Keying and
USB-to-Serial COM4 for radio control, because the current
combination of WriteLog 10.47E and Orion 3.170 requires
two COM ports.
But I measured a 2.1 second delay in changing frequency
using the USB-to-Serial COM port for the rig, so on
Saturday morning, I exchanged ports and measured the
rig control delay at about .95 seconds with the internal
COM port, and didn't notice any problems keying the rig
with the USB to Serial for a couple of hours.
Until I accidentally hit an unknown combo of keys, and
key combo that gave me the blue screen.
On my second blue screen, I reverted back to using
USB-to-Serial for rig control, internal COM for CW,
and experienced no further problems nor blue screens,
and learned to tolerate the 2 second rig change time.
