Appendix B FAQ

A few frequently-asked questions

B.1 How do I do this?

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

can change the following features using the following command steps:

B.1.1 Change Port Parameters

Serial Port settings are modified via the stty command (see man page stty). The

serial port settings must be modified in the rc.serial file in order to be permanently

changed. Note the following:

• Changing port names is persistent over a reboot

• Changing port communication settings (baud rate, parity etc.) is tem-

porary - the file /etc/rc.serial must be edited in order to save the

settings

To change the Port Parameters, you edit the file:

/etc/rc.d/rc.serial

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

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

B.1.2 Change the Name of a Port

You can change the name of a Port if you know the original name. For example,

to change the Port <current name> to “payroll”, you enter:

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