Hi Experts:

   The following relates to X86/2.5/du 3.  

   I can't get stty to work form me.  What am I doing wrong?  

   I enter:
$ stty parenb -parodd 2400 cs7 cstopb crtscts < /dev/tty00

   I believe this should enable parity, set it to even, 2400 BPS,
7 bit data, 2 stop bits, RTS/CTS handshake.  Yes, I know this a weird
way to set a port.  I'm just testing my ability to talk to any
configuration.  

   I then test the serial port:
$ stty -a < /dev/tty00                                    
speed 9600 baud;
rows = 0; columns = 0; ypixels = 0; xpixels = 0;
eucw 1:0:0:0, scrw 1:0:0:0
intr = ^c; quit = ^|; erase = ^?; kill = ^u;
eof = ^d; eol = <undef>; eol2 = <undef>; swtch = <undef>;
start = ^q; stop = ^s; susp = ^z; dsusp = ^y;
rprnt = ^r; flush = ^o; werase = ^w; lnext = ^v;
-parenb -parodd cs8 -cstopb -hupcl cread -clocal -loblk -crtscts -crtsxoff -parext
-ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -iuclc
ixon -ixany -ixoff imaxbel
isig icanon -xcase echo echoe echok -echonl -noflsh
-tostop echoctl -echoprt e*-defecho -flusho -pendin iexten
opost -olcuc onlcr -ocrnl -onocr -onlret -ofill -ofdel tab3
$

   It loooks like nothing I set made an impression.  

   I can tcsetattr from my application to set any of these options just
fine.  But I want to set BPS, parity, and other serial port values from
the comand line.  Then call the application, which will set a few
additional port values, but not those I want to set from the command line.  

   I can set the port from the application when I'm in user.  I've tried
stty as a user and root.  No luck in either case.  

   Suggestions?  

                                                                    Thanks

You'd need to keep the port open for the stty to stick.

Of course, you have to kill the sleep process, when you are finished. :-)
