A.5 Enabling Braille

To enable your system to support Braille output, you must configure the access rights to the serial port to which the Braille device is connected. The following sections describe the steps that you need to perform depending on your operating system.

A.5.1 To Enable Braille on Solaris Systems

To configure the serial port to which the Braille device is connected on Solaris systems, perform the following steps:

  1. Log in as the root user.

  2. Enter the following command:

    chmod 777 /dev/cua/a

  3. Enter the following command:

    chmod 777 /dev/cua/b

  4. Change the permissions to 777 on the devices to which the symbolic links /dev/cua/a and /dev/cua/b point.

Note –

If your system uses /dev/cua/a for system log messages, Braille will not work on that serial port. Use /dev/cua/b instead.

A.5.2 To Enable Braille on Linux Systems

To configure the serial port to which the Braille device is connected on Linux systems, perform the following steps:

  1. Log in as the root user.

  2. Enter the following command:

    chmod 777 /dev/ttyS0

  3. Enter the following command:

    chmod 777 /dev/ttyS1
