Verifying Serial Port Settings on TTYB

This procedure lets you verify the baud rate and other serial port settings used by the Netra 440 server to communicate with a device attached to its ttyb port.

Note – The serial management port always operates at 9600 baud, 8 bits, with no parity and 1 stop bit.

You must be logged in to the Netra 440 server, and the server must be running Solaris OS software.

To Verify the Serial Port Settings on TTYB

1.Open a shell tool window.

2.Type:

#eeprom grep ttyb-mode

3.Look for the following output:

ttyb-mode = 9600,8,n,1,-

This line indicates that the Netra 440 server’s serial port ttyb is configured for:

9600 baud

8 bits

No parity

1 stop bit

No handshake protocol

For more information about serial port settings, see the eeprom man page. For more information about the ttyb-modeOpenBoot configuration variable, see Appendix A.
