Thanks for the response, an explanation of the command syntax copied from WA6HHQ.
Unfortunately, this information only tells me that there's an embedded command prefix before a string sent to the control port on the K2, to get it to send in CW what's coming next. The information does not tell me how to redirect this string to the TXD line for rig control, within DX4WIN. DX4WIN can toggle several handshaking lines on the rig control serial cable for CW keying, as well as toggle a separate serial port for the same effect. Neither of these methods will work with the K2, at least not via the com port. I could build a diode-or adapter to parallel a conventional serial port keyer with the Elecraft's key input. However, I would prefer that the premier logging / station control program on the market would support the Kenwood/Elecraft "serial CW" mode. If it does and I have missed it in the documentation, please tell me what I'm doing wrong... 73 Steve KZ1X/4
