Serial Console speed/tty
The AstLinux board type of “geni586-serial” assumes a serial console of 19200 baud on /dev/ttyS0 . Described here is a method to change the serial console speed/tty, not only currently but also automatically after upgrades.
This applies to the board type of “geni586-serial” and all other serial console board types, “net5501”, “alix”, etc. .
Note: AstLinux 1.0.4 or later is required
After setting-up AstLinux and creating the persistent storage, the setconsole-speed-tty
command is used to make changes to the serial console speed/tty settings.
Usage: setconsole-speed-tty [ show|reset|help ] 9600|19200|38400|57600|115200 [ ttySn ]
Set console speed to 38400 baud, using default ttyS0
setconsole-speed-tty 38400
Set console speed to 115200 baud, using /dev/ttyS1
setconsole-speed-tty 115200 ttyS1
Display current settings
setconsole-speed-tty show
Reset /etc/inittab to default factory state with matching kernel console= values
