I follow the Tutorial to connect a switch,
use ls *usb*
I can find the usb:
$ ls *usb*
cu.wchusbserial1410
tty.wchusbserial1410
I connect to it:
screen tty.wchusbserial1410 9600
but I get the messy code when I type the keyboard.
I type enter, there gets the ?
, I type s, there will get f
. you can see in the snapshot:
EDIT-01
My switch is Juniper-EX4300 and the usb driver is Qinheng.
and the Juniper manual shows the Baud rate is 9600
.
EDIT-02
I use the console-serial line connect the switch port, and then use the serial-USB convertor connect the line and my Mac.
