DtrControl and RtsControl have double bits so it should be as mask
in same struct.inc you can see
function fDtrControl(var a : DCB) : DWORD;
begin
fDtrControl:=(a.flags and bm_DCB_fDtrControl) shr bp_DCB_fDtrControl;
end;
How could I have missed that? I did not seek to interpret what the bm_
and bp_ were. Thanks for pointing that out.
Consequently, bm_DCB_fRtsControl ($3000) and bm_DCB_fDtrControl ($30)
are correct.
here fDtrControl return a number 0..3 as DWORD not boolean.
for your code is wrong becuase dtrcontrol/rtscontrol have 4 state not
one as you use it
True, but we do not need to expose the programmer to all of these
states, do we? For example, in the Com port settings (Windows device
manager), available options for the flow control (handshaking) are:
None
XOn/XOff
Hardware
What does hardware represent in terms of these flags?
Thanks
