[WriteLog] CW direct keying

[Darren Collins (G0TSM)]

I re-hooked up the direct keying interface and tried changing the 
priority in the Windows task manager, but it made no difference, same 
issue kept cropping up, even with anti-virus disabled on the 
near-vannilla Win7 32bit installation. Incidentally it is the same for 
RTTY but is harder to hear the problem when TXing, the rtty QSOs were 
taking longer due to callers repeating their exchanges as I was sending 
un-decodable replies.
As a test I tried Logger32 directly keying the same interface in CW and 
RTTY (it's a dual rtty/cw direct keying interface) and that ran smoothly 
so i'll need to do some more investigating.
