True.  You can use the CATA1ASC command in any N1MM function key macro 
to send commands ... any commands you want.  For SS SSB, I record my CQ 
and exchange in the K3 DVK memory and then use the function keys to send 
SWTxx commands to emulate tapping the M1 or M2 keys.

I believe so.

Yes.  Be aware however that the 9-pin D connector on the back of the K2 
is *NOT* an RS-232 serial port.  3 pins [Gnd, RX data, and TX data] are 
RS-232 levels.  The other pins are not.  Do not plug the USB-serial 
adapter directly into the K2 port.

Yes, and it works fine, subject to the usual disclaimers about Prolific 
vs FTDI vs Chinese knock-off USB adapters.
