Description
D—Full dump; implies s as well. By default, if
Tru64 UNIX crashes, it completes a partial
memory dump. Specifying D forces a full dump at
system crash.
Common settings are a, autoboot, and Da,
autoboot and create full dumps if the system
crashes.
Sets the baud rate of the COM1 (MMJ) port. The
default baud rate is 9600.
Baud rate values are 1800, 2000, 2400, 3600,
4800, 7200, 9600, 19200, 38400, 57600.
Sets the baud rate of the COM2 port. The default
baud rate is 9600.
Baud rate values are 1800, 2000, 2400, 3600,
4800, 7200, 9600, 19200, 38400, 57600.
The com1_flow and com2_flow environment
variables indicate the flow control on the serial
ports. Defined values are:
none—No data flows in or out of the serial ports.
Use this setting for devices that do not recognize
XON/XOFF or that would be confused by these
signals.
software—Use XON/XOFF(default). This is the
setting for a standard serial terminal.
hardware—Use modem signals CTS/RTS. Use
this setting if you are connecting a modem to a
serial port.
Specifies the COM1 data flow paths so that data
either flows through the RMC or bypasses it.
