– Eight bits per character
– One stop bit per character
– Parity disabled (no parity)
– Baud rate 9600 baud (the power-up default)
After power-up, you can reconfigure the baud rate of the debug port
by using the 172Bug Port Format (PF) command.
Whatever the baud rate, some form of hardware handshaking —
either XON/XOFF or via the RTS/CST line — is desirable if the
system supports it. If you get garbled messages and missing
characters, you should check the terminal to make sure that
handshaking is enabled.
13. If you have equipment (such as a host computer system and/or a
serial printer) to connect to the other EIA-232-D port connectors
(marked
SERIAL PORT
connect the appropriate cables and configure the port(s) as detailed
in Step
12
above. After power-up, you can reconfigure the port(s)
by programming the MVME172P4 Z85230 Serial Communications
Controller (SCC) or by using the 172Bug PF command.
14. Power up the system. 172Bug executes some self-checks and
displays the debugger prompt
mode.
However, if the ENV command has placed 172Bug in System
mode, the system performs a self-test and tries to autoboot. Refer to
the ENV and MENU commands
If the confidence test fails, the test is aborted when the first fault is
encountered. If possible, an appropriate message is displayed, and
control then returns to the menu.
15. Before using the MVME172P4 after the initial installation, set the
date and time using the following command line structure:
SET [mmddyyhhmm]|[<+/-CAL>;C]
172-Bug>
For example, the following command line starts the real-time clock
and sets the date and time to 10:37 a.m., November 7, 2000:
on the MVME712x transition module),
if the firmware is in Board
172-Bug>
(Table
3-2).
