Connecting a Mac to a 10G switch via a USB connected console cable and while using screen command (with the right baud rate), access to the console shows incorrect characters.
To work around this issue, use picocom instead of screen.
Install picocom on your Mac and run:
picocom -b 115200 --send-cmd "sx -vv" /dev/ttyXXXX
Further, if you are using FTDI or Prolific USB to serial adapters to access the switch console from OSX, you may experience one of the following problems:
- Kernel panic of OS X upon removing the adapter from the USB port
- Data is received only under screen or cu (although it may work as expected in a virtual machine on OSX)
USB to serial adapters that work properly include those based on the PL2303 device.
This issue was reported originally in ticket #45.
