8.Redirect the input and output to the screen and keyboard, if needed, by typing:

ok screen output keyboard input

Note –When entering ~ (tilde character) commands in the tip window,

the tilde must be the first character entered on the line. To ensure that you are at the start of a new line, press Return first.

How to Verify the Baud Rate

To verify the baud rate between the Sun Fire 280R server and a terminal or another Sun system monitor:

1.Open a shell window.

2.Type eeprom.

3.Verify the following serial port default settings as follows:

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

Note –Ensure that the settings are consistent with TTY-type terminal or system monitor settings.

Common Problems With tip Connections

This section describes solutions for tip problems occurring in Solaris Operating Environments versions previous to 2.0.

Problems with tip may occur if:

■The lock directory is missing or incorrect.

There should be a directory named /usr/spool/uucp. The owner should be uucp and the mode should be drwxr-sr-x.

■The ttyb serial port is enabled for logins.

The status field for ttyb (or the serial port you are using) must be set to off in /etc/ttytab. Be sure to execute kill -HUP 1 (see init(8)) as root if you have to change this entry.
