3.2.1Setting Up a Tip Connection

A tip connection enables a remote shell window to be used as a terminal to display test data of a system being tested. Serial port A or serial port B of a tested system unit is used to establish the tip connection between the system unit being tested and another Sun workstation monitor or TTY-type terminal. The tip connection is used in a SunOSTM window and provides features to help with the OBP.

To set up a tip connection:

1.See FIGURE 3-1. Connect serial port A of the system being tested to serial port B of another Sun workstation using a serial null modem cable (connect cable pins 2-3, 3-2, 7-20, and 20-7).
