PR 501/rtems_misc

• console.c: console_open disables ICANON on non-console port, which should be ok for the first open but not for subsequent ones. If you open one serial port, you will configure it, when you reopen it you will lost the ICANON parameters if you had put it. Should be done by console only at first open.
