[Elecraft] K3 CW Keying via Serial Port?

[Rick Tavan N6XI]

It all depends on the computer and the load on it. I've used serial port
keying for years with a variety of computers. With faster computers and
light load other than the logging program, it works fine. With a heavy load
of extraneous I/O, like a telnet spotting network during Sweepstakes, I
experienced occasional aggravating timing glitches that made it difficult to
send at high speed and disrupted computer sending. So I switched to WinKey
which eliminates the problem.
