6. Using Serial SAMs
The Serial SAM is a serial-to-VGA converter which permits VT100-capable devices to be
viewed from the KV171xA user station. 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 KV171xA user station as though it
came from a VGA target device. Likewise, keystrokes entered on a keyboard are sent to
the attached device as though they were typed on a VT100 terminal.
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.
• Configuration: This mode enables you to specify communication parameters, the
appearance of the serial data, key combinations for specific 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 Configuration Screen, which contains menu items that
allow you to configure your Serial SAM.
NOTE:
When the Configuration 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
bauds 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 flow 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 available Flow
Control is
RTS/CTS (hardware).
• DSR/CD Mode: This option allows you to control the Data Set Ready/Carrier Detect
line on your serial interface. Available options are Always on and Toggle. The default
value is Always on.
• Enter Sends: This option enables you to specify the keys that are transmitted when
Enter is pressed. Available options are <CR> (Enter) or <CR><LF> (Enter
-
Linefeed).
• Received: This option enables you to specify how the module translates a received
Enter character. Available options are <CR> (Enter) or <CR><LF> (Enter
-
Linefeed).
