Out-of-Band Mgmt
Port
Microsoft Windows Emergency Managment Services (EMS) allows for remote
managment of a Windows Server OS through a serial port. This setting allows
you to specify which port to use (COM1 or COM2).
Terminal Type
VT-UTF8 is the preferred terminal type for out-of-band management. The next
best choice is VT100+ and then VT100. Options include ANSI (extended ASCII
character set), VT100 (ASCII character set), VT100+ (extends VT100 to support
color, function keys, etc.) and VT-UTF8 (uses UTF8 encoding to map Unicode
characters onto one or more bytes).
Bits per Second This setting selects the serial port transmission speed, which must be matched
on the other side. Long or noisy lines may require lower speeds. Options include
9600, 19200, 57600 and 115200.
Flow Control
Flow control can prevent data loss from buffer overflow. When sending data, if
the receiving buffers are full, a ‘stop’ signal can be sent to stop the data flow.
Once the buffers are empty, a ‘start’ signal can be sent to re-start the flow.
Hardware flow control uses two wires to send start/stop signals. Options include
None, Hardware RTS/CTS and Software Xon/Xoff.
