[Elecraft] K3 manual question

[K4FJ at aol.com]

Hi,
 
Page 18 of my K3 manual shows the breakout for the RS232 connector.   It says 
pin 6 is RTS.  I thought RTS was on pin 7 in the standard DB9  configuration.
 
Second question:  The manual is clear that pin 1 of the Aux I/O  connector is 
for FSK IN.  Does that mean that I run my computer's RS232 pin  3 (txd) or 4 
(dtr) through a NPN level adjuster, or either?
 
Third question:  I am confused because I read (in the manual) that  Config: 
PTT-KEY settings address only OFF or DTR/RTS or RTS/DTR.  No  mention of TXD.  
Does KEY relate only to CW and not FSK/RTTY?
 
Just another non-computer jock trying to keep up.
 
This reflector, Elecraft, and the K3 are just great.
