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.
