F6 sends its expected function key control sequence, and the terminal 
driver intercepts and converts that to ^C, and SET TERMINAL 
/NOLINE_EDIT is one way to disable that driver conversion.

I don't recall if there's a (more) targeted means to disable (just) F6 
conversion within the terminal driver itself, short of patching the 
driver or such, and, yes, /NOLINE_EDIT is a fairly large hammer.

Or tweak the terminal emulator to send something other than (in eight 
bit) CSI 1 7.

VT terminals treat the first clump of DEC OpenVMS LK-layout function 
keys as local, so most of OpenVMS tends not to expect to ever see F1, 
F2, F3, F4, or F5.

For some of the usual code for fielding ^C and ^Y, see:
