That is why it is necessary to set:

rtty send string = tc<0D>x<0D>

So as to clear the transmit buffer of whatever it is that the PK232 thinks it
got from TR after the ^D to put it back into receive.

You don't want to change F10 from default - it is the key that puts you 
into keyboard
send mode (hitting it sends RTTY SEND STRING, after which PK232 is in transmit
& converse modes, which means subsequent text gets sent as TR is then in 
terminal
mode, when done you hit <ESC> & TR sends the RTTY RECEIVE STRING & drops
back out of terminal mode).
