Appendix C: Using Serial IQ Modules
The serial IQ module is a serial-to-VGA converter that allows VT100-capable devices to be viewed from
the switch local port, the OBWI or by using the switch software. All serial data coming from the device is
read-only. The data is displayed in a VT100 window, placed into a video buffer and sent to the switch as
though it came from a VGA device. Likewise, keystrokes entered on a keyboard are sent to the attached
device as though they were typed on a VT100 terminal.
C.1 Serial IQ module modes
The following modes can be accessed from the serial IQ module:
•
On-Line: This mode enables you to send and receive serial data.
•
Configuration: This mode enables you to specify switch communication parameters, the
appearance of the Terminal Applications menu and key combinations for specific actions and
macros.
•
History: This mode enables you to review serial data.
C.2 Configuring the serial IQ module
NOTE: The serial IQ module is a DCE device and only supports VT100 terminal emulation.
Pressing
Ctrl-F8
activates the Configuration window of the IQ module’s Terminal Applications menu, which
enables you to configure your serial IQ module.
NOTE: When any Terminal Applications menu is active, pressing Enter saves changes and returns you
to the previous window. Pressing Escape returns you to the previous window without saving changes.
Within the Terminal Applications menu’s Configuration window, you can modify the following options:
•
Baud Rate: This option allows you to specify the serial port communications speed. Available
options are 300, 1200, 2400, 9600, 19,200, 34,800, 57,600 or 115,200 bps. The default value is
9600.
•
Parity: This option allows you to specify the communications parity for the serial port. 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 bps rate of 115,200, the only available flow control is RTS/CTS (hardware).
•
Enter Sends: This option enables you to specify the keys that are transmitted when Enter is
pressed. Available options are CR (Enter), which moves the cursor to the left side of the window
or CR LF (Enter-Linefeed), which moves the cursor to the left side of the window and down one
line.
•
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).
•
Background: This option changes the window’s background color. The currently selected color
displays in the option line as it is changed. Available colors are Black, Light Grey, Yellow, Green,
Teal, Cyan, Blue, Dark Blue, Purple, Pink, Orange, Red, Maroon and Brown. The default color is
Black. This value cannot be identical to the Normal Text or Bold Text value.
•
Normal Text: This option changes the window’s normal text color. The currently selected color
displays in the option line as it is changed. Available colors are Grey, Light Grey, Yellow, Green,
Teal, Cyan, Blue, Dark Blue, Purple, Pink, Orange, Red, Maroon and Brown. The default color is
Grey. This value cannot be identical to the Bold Text or Background value.
