unable to get agetty to work at 115200 baud - Raspberry Pi Forums

-

i have rpi3b , i'm running raspbian stretch.

goal login via usb-to-serial adapter using ssh @ 115200. working @ 9600. when attempt login @ 115200, no prompt appears. ssh session blank.

have done following:

0. apt-get update, apt-get upgrade, apt-get dist-update done.
1. /boot/config.txt contains enable_uart=1
2. agetty used service: execstart=-/sbin/agetty --keep-baud 115200,38400,9600 %i $term
3. /dev/ttyusb0 explicitly set 115200: sudo stty -f /dev/ttyusb0 115200
4. know /dev/ttyusb0 working @ 115200 because if connect minicom /dev/ttyusb0, can send , receive characters @ 115200.

ideas solution or next step?

regards,radiokk6
