John,
Depends on the program. Most use serial port keying; works even if you are
using a USB-serial converter which I am doing right now. For example, MixW
lets you select either DTR or RTS for PTT or CW, but some programs use one
for CW and one for DTR but not both for both.. I don't use DRT, because at
the time I made up my interface one of the Windows operating systems DRT
keyed on startup. You can get around this by turning off the K2 on
computer start up. I am making up a new interface and diode "ORing" both
DTR and RTS to both the K2 keying line and the K2 PTT so it will work no
matter which program I use. The K2 key also needs to be diode ORed to both
the dot and dash connections per K2 manual and the K2 menu setup made so
the computer keying will work. I have a paddle plugged to the interface
that bypasses the diodes on the CW keying circuit so the paddle works or CW
keying works, which ever gets there first.

I wonder if other K2 owners (with the KI02 option of course!)
are using computer keying? If so, did you implement
it using the DTR or PTT method via the serial port, or
via the parallel port? Are there advantages to one method over another?
Thanks!
