Jim,

See the K2 Programmer's Reference for all the commands that can be 
sent/received via the K2 through the KIO2 interface.  Keying uses the KY 
command, and in SSB or RTTY mode, the TX command will set the transmit 
state (pulls PTT low).
If your software application can issue those commands, then it is 
possible - if the commands are not available, all you can do is appeal 
to the applications author to include that support - I don't know those 
specid\fics of MixW.

Please resist the temptation to refer to the K2 AUX I/O as an RS-232 
port - it is NOT, even though it contains TXD, RXD and Signal Ground as 
RS-232 signaling levels.  Other pins are used for internal K2 signals 
that are used by other Elecraft devices such as the KAT100 and the 
KRC2.  Connecting a standard computer serial cable to this AUX I/O 
connector can damage your K2.  Just because it uses a DE-9 connector 
does not make it a serial port (that should true for any device using a 
similar connector - if it is not marked as an RS-232 connector, it 
probably is not, check the manual for the device first).

73,
Don W3FPR
