Hi!

    Question: by default, only CON device have bits "stdin" and "stdout"
 

yes, at boot only the ORIGINAL CON device has these bits (subsequent 
CONs could make this to change and gain these bits).

(mask 0x3 in attribute word). What happen if I use "CTTY NUL" - is this
equal to plain redirecting to NUL or shell sets stdin+stdout bits in
attribute word (INT 21/4401, as I understand)?
 

Also remember that in the lists of lists you have:
0Ch DWORD pointer to active CON device's header (most recently loaded 
driver with STDIN bit set)

This is a pointer to stdin, guess that it has to be changed too.
