This section is a collection of tips and hints for various setup items. The root user can change

any of the following features using the given command steps:

B.1.1 Change Port Parameters

Serial Port settings are modified via the stty

command (see man

The serial port

settings are modified in the rc.serial

file to be permanently changed. Note the following:

• Changing port names is persistent over a reboot

must be edited in order to save the settings.

To change the Port Parameters, edit the file: /etc/rc.d/rc.serial

For example, to change the baud rate for Port 5 to 19,200 baud, enter:

Stty -F/dev/ttyB5 19200 {other options}

B.1.2 Change the Name of a Port

Port <current name> to payroll, enter:

Stty --name=payroll -F/lsi/ports/<current name>
