stty and /dev/com1


Hello,

I thing that something is wrong with stty command this are listings from
Cygwin:

$ stty -F /dev/com1
speed 9600 baud; line = 0;
intr = <undef>; quit = <undef>; erase = <undef>; kill = <undef>; eof =
<undef>;
susp = <undef>; rprnt = <undef>; werase = <undef>; lnext = <undef>;
flush = <undef>; min = 0; time = 0;
-cread
-brkint -icrnl -imaxbel
-opost -onlcr
-isig -icanon -iexten -echo -echoe -echok -echoctl -echoke
$

(Then i try to start the reciver)

$ stty -F /dev/com1 cread
stty: /dev/com1: unable to perform all requested operations
$
What dose it means ? Why can't  i start reciver ? I have big problem with
modem communication.
