8: Using a Serial SAM
The serial SAM is a serial-to-VGA converter which permits VT100-capable devices
to be viewed from the ServSelect IP local port or by using the ServSelect IP
software. The actual serial data is not accessed, but is merely displayed. All serial
data coming from the target device is displayed in a VT100 window, placed into a
video buffer and sent to the ServSelect IP appliance as though it came from a VGA
server. Likewise, keystrokes entered on a keyboard are sent to the attached device as
though they were typed upon a VT100 terminal.
NOTE:
The serial SAM requires an additional power supply (PS123A or PS123E).
Serial SAM modes
The following modes can be accessed from the serial SAM:
• On-Line - This mode enables you to send and receive serial data.
• History - This mode enables you to review serial data.
• Confi guration - This mode enables you to specify communication parameters,
the appearance of the serial data, key combinations for specifi c actions and
macros.
Configuring the Serial SAM
NOTE:
The Serial SAM is a DCE device and only supports VT100 terminal emulation. Pressing Ctrl-F8
will activate the Confi guration Screen, which contains menu items that allow you to confi gure
your serial SAM.
NOTE:
When the Confi guration Screen is active, pressing Enter saves changes and returns you to the
previous screen. Pressing Esc returns you to the previous screen without saving changes.
Within the Configuration Screen, you can modify the following options:
• Baud Rate - This option allows you to specify the serial port communications
speed in bits per second (BPS). Available options are 300, 1200, 2400, 9600,
19200, 34800, 57600 or 115200. The default value is 9600.
• Parity - This option allows you to specify the serial port communications parity.
Available options are EVEN, ODD or NONE. The default value
is NONE.
• Flow Control - This option allows you to specify the type of serial fl ow control.
Available options are NONE, XOn/XOff (software) and RTS/CTS (hardware).
The default value is NONE. If you select a baud rate of 115200, the only avail-
able fl ow control is RTS/CTS (hardware).
