After power-up, you can reconfigure the baud rate of the
debug port if necessary by using the 162Bug firmware's Port
Format (PF) command.
Note
In order for high-baud rate serial communication
between 162Bug and the terminal to work, the terminal
must do some form of handshaking. If the terminal
being used does not do hardware handshaking via the
CTS line, then it must do XON/XOFF handshaking. If
you get garbled messages and missing characters, then
you should check the terminal to make sure
XON/XOFF handshaking is enabled.
8. If you want to connect devices (such as a host computer
system and/or a serial printer) to the other EIA-232-D port
connectors, connect the appropriate cables and configure the
port(s) as detailed in step 4 above. After power-up, you can
reconfigure this (these) port(s) by programming the
MVME162LX Z85230 Serial Communications Controllers
(SCCs), or by using the 162Bug
9. EPROM/Flash configuration header J20 should be set to
configuration 2, with jumpers between J20 pins 5 and 6, 8 and
10, and 9 and 11. This sets it up for 512K x 8 EPROMs.
10. Power up the system. 162Bug executes some self-checks and
displays the debugger prompt
162-Bug>
(if 162Bug is in Board Mode). However, if the
(Appendix A) has put 162Bug in System Mode, the system
performs a selftest and tries to autoboot. Refer to the
commands (Table 4-3).
