[Dx4win] Sending Control Codes in RTTY Window with TNC

[WK0F]

Hi,
I used to have a Kam and tried some of the other multimodes. I have 
decided to go back to a KAM and can't recall how to program in the 
control codes.  Anyone out there have some examples of  how they use 
their TNCs in the RTTY window.  I am specifically looking for :
Control T (transmit)
Control E (go to receive after message is sent)
Control R (force receive)

I have looked in the help files.  I thought %CT would work for 
transmit,  but no joy.  If I can't embed these control keys into the 
messages, I guess I could set up an F key for these functions.
TIA es 73,
Terry, WK0F
