Console Redirection
Overview
Console, or serial, redirection allows an SBC or motherboard to be installed at a remote
location, operating the platform via a serial terminal. Redirection does not require a
video controller or keyboard in order to operate.
Interrupts
Console redirection utilizes two (2) interrupts:
•
Video
: Redirection uses the video interrupt (10h) to detect any video operations not
made by direct screen memory or an I/O controller.
Note:
Because the redirection service sends ASCII data to the serial terminal, only
text can be supported, not graphics.
•
Keyboard
: Redirection uses the keyboard interrupt (16h) to receive characters sent
from the serial terminal and convert them to the appropriate PC scan codes.
Note:
Operating systems or applications that do not use the interrupt 16h services
will require a redirection driver to receive data from the serial terminal.
Configuration
The procedure for enabling console redirection is outlined in the following table:
Cable
For proper operation of most serial terminals, it is strongly recommended that signals
from each end of the serial cable be configured as listed below:
Note:
The Ring Indicator (RI) signal can be ignored.
Step
Action
1
Run the Setup Utility. See
.
2
Provide a serial port for console redirection.
Note:
A serial port on the SBC can be used for console redirection.
See
. A serial I/O expansion card can also be used.
3
Select the address and interrupt for the serial port.
4
Set the console redirect port to the same address and interrupt that was
selected in step 3. See
5
Set the baud rate for the console redirect port.
Note:
This must match the baud rate of the serial device.
6
Connect the serial cable between the redirection port and the serial terminal.
Note:
Redirection uses XON and XOFF for flow control. For a simple
connection, a three-wire serial cable can be used. Only Ground, Transmit, and
Receive signals are required.
Note:
Console redirection will function once the CPU is reset.
The Setup Utility can be accessed through console redirection. However, it is
rather slow because the setup screens are graphical, and each change
requires the entire screen to be redrawn.
The Adaptec SCSI Setup Utility is not accessible via console redirection.
