usb serial not able to set the speed using stty

[learner24]

Trying to change the speed of usb-serial port as follows

stty -F /dev/ttyGS0 115200

and the following error is seen.

stty: /dev/ttyGS0: unable to perform all requested operations

It works only for B9600. For all other speeds it just reports the above error.

Is there a way to change the speed ?

Hi Raju,

Are you using a NXP board and BSP?

Have you ensured that such serial interface does support the desired speeds? How about checking permissions of the TTY?

Hope this will be useful for you.
Best regards!
