Terminal Type
VT-UTFB Combo Key Support
Select the terminal types.
Enable or disable the support of VT-UTFB combination key for ANSI/VT100 terminals.
VT100
ASCII char set
VT100+
Extend VT100+ to support color, function keys, etc.
VT-UTFB
Use UTFB encoding to map the unicode chars onto 1 or more bytes.
ANSI
Extend ASCII char set
Recorder Mode
Bits per second
On the Legacy OS, the number of Rows and Columns supported redirection.
Select the transmission speed of the serial port. The speed must be matched on the
other side. Long or noisy lines may require lower speeds.
Putty KeyPad
Text will be sent on the Enabled mode to capture the terminal data.
Resolution 100x31
Enable or disable the extended terminal resolution.
Legacy OS Redirection Resolution
Select the function key and key pad on Putty.
Data Bits
Redirection After BIOS POST
Enter the value for data bits.
The settings specify if BootLoader is selected than Legacy console redirection which is
disabled before booting to the Legacy OS. Default value is Always Enable which means
that Legacy Console Redirection is enabled for the Legacy OS.
Parity
A parity bit can be sent with the data bits to detect some transmission errors.
Even
Parity bit
Odd
Parity bit
Mark
Parity bit
Space
Parity bit
is 0 if the num of 1’s in the data bits is even.
is 0 if the num of 1’s in the data bits is odd.
is always 1.
is always 0.
Mark and Space parity do not allow for error detection.
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.
Flow Control
Flow control can prevent the data losss from the 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. The hardware
flow control uses two wires to send start/stop signals.
