Serial Port Parameter

[Oleg_23]

Hi.
Sorry for my English.

I have HP9000 server L-series, HP-UX 11i.
Server has IO-Core card with 3 serial ports (remote, console, power).

How can I change speed for a serial port, e.g. /dev/tty0p0?
By default, speed is 300 baud:

$ stty < /dev/tty0p0
speed 300 baud; ...

I try -

$ stty 9600 < /dev/tty0p0

but speed did not change.

If I change speed in GSP, anyway nothing happened.

Thank you in advance.

Hi!

Your stty command is perfectly correct. But the configuration is reset to its defaults when the device is closed. You need to keep it open while you need to use it.

From a posix-sh script e.g.:

(
stty 9600
echo "hallo"
read answer
...
) < /dev/tty0p0 >/dev/tty0p0


Regards...
Dietmar.

OR


sleep 9999999999> > /dev/tty0p0&

stty 9600 < /dev/tty0p0

Oleg,

If that's poor english, I can't imagine what correct english is!

Maybe it was those cryptic commands, like:

stty


:-)
