====== 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:

  Usage: setconsole-speed-tty [ show|reset|help ] 9600|19200|38400|57600|115200 [ ttySn ]

\\
To issue this command you must either SSH into the AstLinux box, or use the CLI tab in the web interface with the "CLI Proxy Server" enabled in the Network tab.  Some example command arguments are:

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
  setconsole-speed-tty reset
