Meaning
This item allows you to set the transmission speed in bits per second.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
❖
This item allows you to set the length of each word (in bits) being transmitted.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
❖
This item allows you to set the type of parity, if any, that has been added to the transmission.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
❖
This item allows you to set the number of stop bits added to the transmission.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
❖
This item allows you to select the flow control for the serial port. Flow control is the ability of one device (the
slower device) to tell another device (the faster device) to stop sending data. Flow control can be managed
by hardware (a signal sent on one of the serial port pins) or software (a special character sent to the faster
device).
The choice of Hardware or Software flow control depends on the device that you are connecting to the Matrox
Supersight unit (see the device's hardware manual).
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
❖
This item allows you to enable 8-bit Unicode transformation format (UTF-8) support for ANSI and VT100
terminals.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
❖
This item allows you to enable logging of the terminal emulation sessions.
When set to Enabled, text is sent to the serial port. This item is used to send the entire current row of data
displayed on the terminal (for example, to send the line of the BIOS menu with which you are interacting).
When set to Disabled, no text is sent.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
❖
This item specifies whether the size of the region of data sent is 100 columns by 31 rows. Typically, when
dealing with a modern operating system, this item is used by your terminal emulation program to determine
the screen resolution.
When set to Disabled, the resolution is 80x25.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
