vSee the operator manual for your type of TTY terminal to find the key sequences you need to respond to the diagnostics.
vWhen the diagnostics present display information through the S1 serial port, certain attributes are used. These attributes are set as if the diagnostics were using a 3161 display terminal. Refer to the tables in Appendix C, ªGeneral Attributes Required When Using a TTY Terminalº on page 173 for a list of attributes for the 3161 ASCII Display Terminal and for two other ASCII display terminals commonly used with the system.
vIf you have a TTY terminal other than a 3151, 3161 or 3164 attached to the S1 serial port, your terminal may have different names for the attributes. Refer to the tables in Appendix C, ªGeneral Attributes Required When Using a TTY Terminalº on page 173, and use the attribute descriptions to determine the settings for your terminal.
