Description
Set the times during system operation when EMP access
over the specified port is available. The choices are:
•
Pre-boot only. The EMP is automatically activated
when the system is powered off and during POST.
•
Always Active. The serial port is always dedicated
for EMP use.
•
Always Disabled. The EMP is deactivated.
Enables or disables restricted mode access. When
restricted mode is enabled, control operations that could
disable or alter a running system via the EMP are
disabled.
Configures the method to connect to the EMP:
•
Direct Connect Mode is for applications that
connect the EMP port directly to another computer
system.
•
Modem Mode is for applications that connect the
EMP port to an external modem.
Enables or disables monitoring of the Data Carrier Detect
(DCD) signal. When DCD Mode is enabled, the EMP is
activated and/or reinitialized whenever the serial port's
DCD signal becomes de-asserted.
Configures the maximum rate in bits per second that data
is transmitted through the EMP port. Baud rates are
19200, 38400, 57600, and 115200.
You can disable the flow control or set it to CTS/RTS.
The initialization string is transmitted every time the
EMP initializes. The maximum length is 32 bytes and it
is usually set to "ATE1Q0V1X4&D2&C1S0=0".
The Hangup String is sent to the modem when the EMP
terminates the session. The EMP automatically sends an
<Enter> character after this string. The maximum
length is 8 bytes and it is usually set to "ATH".
