Parameter
Description
COM1/COM2 Serial LAN/
Legacy/Serial Port for Out-
of-Band EMS Console
Redirection Settings
(continued)
Bits per second
– Selects the transfer rate for console redirection.
– Options available: 9600, 19200, 38400, 57600, 115200. Default
setting is 115200.
Data Bits
– Selects the number of data bits used for console redirection.
– Options available: 7/8. Default setting is 8.
Parity
– A parity bit can be sent with the data bits to detect some
transmission errors.
– Even: parity bit is 0 if the num of 1's in the data bits is even.
– Odd: parity bit is 0 if num of 1's in the data bits is odd.
– Mark: parity bit is always 1. Space: Parity bit is always 0.
– Mark and Space Parity do not allow for error detection.
– Options available: None/Even/Odd/Mark/Space. Default setting is
None.
Stop Bits
– Stop bits indicate the end of a serial data packet. (A start bit
indicates the beginning). The standard setting is 1 stop bit.
Communication with slow devices may require more than 1 stop
bit.
– Options available: 1/2. Default setting is 1.
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.
– For COM1/COM2 Serial Over LAN:
»
Options available: None, Hardware RTS/CTS. Default setting is
None.
– For Serial Port for Out-of-Band EMS:
»
Options available: None, Hardware RTS/CTS and Software Xon/
Xoff. Default setting is Hardware RTS/CTS.
Legacy Console Redirection Settings
– Selects a COM port to display redirection of Legacy OS and
Legacy OPROM Messages.
– Options available: COM1/COM2 Serial Over LAN. Default setting
is COM1.
Legacy OS Redirection Resolution
