Hi all,

Yes,
--in WIN32.HLP (11 279 097 byte):
the DCB structure 78 byte (+reserved word), and ByteSize offset = 80 bytes
but if I used it in the SetCommState, the result=0
When I (and probably you) use GetCommState, the first dWord 1C 0 0 0 !!!
--GetCommState result:
1C 0 0 0 --DCBlength
B0 4 0 0 --BaudRate
11 30 0 0 0 0 FF FF FF FF ----------- what is this??
8 --ByteSize --offset = 19 (original 70)
0 --Parity
0 --StopBits
11 --XonChar
13 --XoffChar
0 0 0 0 0 ----------- what is this??
If I use BuildCommDCB with 1C length DCB, the result is succes.
The SetCommState, GettCommState are also.
I attached in dcb_try.zip dcb_try.exw. It uses com2 and makes dcb_try.txt
for demo.
I'd like if someone help to understand this.
Thanks

Attila:
I have a suggestion, Why don't you use GetCommState first and this
will fill in your DCB structure with the initial settings of your
of your commport. You might want to copy the structure settings to
a file. Then change one thing at a time, something like the baudrate
and try using SetCommState to see if you get an error. This may make
it easier to find your problem.
