System Configuration and Setup
Description
Specifies a bus probe algorithm for the system. This
setting is fixed and cannot be altered.
Sets the baud rate of the COM1 (MMJ) port. The
default baud rate is 9600.
Baud rate values are 9600, 19200, 38400.
If you change com1_baud to a setting other than
9600, you need to change the RMC baud rate to
match.
Sets the baud rate of the COM2 port. The default
baud rate is 9600.
Baud rate values are 300, 600, 1200, 2400, 4800,
9600, and 19200.
The com1_flow and com2_flow environment
variables indicate the flow control on the serial ports.
Defined values are:
None—No flow control.
Software—Use XON/XOFF (default value).
HARDWARE — Use modem signals CTS/RTS.
Both— Use software and hardware.
Used by the operating system to determine if a
modem is present.
On— Modem is present.
Off—Modem is not present (default value).
Sets the device on which power-up output is
displayed.
Graphics—Sets the power-up output to be displayed
at a graphics monitor or device connected to the
VGA module.
Serial—Sets the power-up output to be displayed on
the device that is connected to the COM1 (MMJ)
port.
Sets the Ethernet controller to the default Ethernet
device type.
aui—Sets the default device to AUI.
bnc—Sets the default device to ThinWire.
fast—Sets the default device to fast 100BaseT.
fastfd—Sets the default device to fast full duplex
100BaseT.
full—Set the default device to full duplex twisted
